[Bug] Unable to update apps via Platform 14.4.3

Some users are experiencing issues updating apps via the current stable platform release. The error given will be similar to:

"Unable to download the file. This could be due to a proxy or network issue or the hosting server not permitting downloads from your location file. File:..."

This issue will require some investigation to solve due to the fact that the updater/app store uses the built-in Windows internet components to handle downloads. As such, we likely have a few issues to work on fixing.

First off, Windows XP users will be unable to update files hosted on SourceForge due to some of the download mirrors only working with newer encryption methods. You can try again and hope you get a different mirror. The more complete solution is called POSReady. This is a registry key patch for Windows XP that will cause Windows Update to treat it as Windows Embedded, which is still supported. You fully update Windows XP SP3, including installing the latest version of IE and applying all updates. Then you apply the POSReady patch and reboot. Then you check Windows update again and apply additional patches released since Windows XP end of life. Note that this method is unsupported and may be illegal in your location.

For users on Vista and later or using Windows XP with POSReady applied, there are other things to check. The first issue we encountered previously was having Internet Options set to warn when http switched to https or vice versa. Platform 14.4.3 and 15 Beta 3 are already mitigating this issue. The second issue we encountered is PCs with secure connections disabled. If you check Internet Options in your Control Panel, click on the Advanced tab and scroll to the bottom, you should have TLS 1.0, TLS 1.1, and TLS 1.2 all checked off (Note that Windows XP/Vista users only have TLS 1.0). If you do not, please check them off now. We'll be mitigating this in the next release to the PA.c Platform as we do with the https to http warning. While in here, it's a good idea to uncheck the Warn if changing between secure and not secure as well as it will prevent issues with apps using Windows internet components.

If you have done the above, rebooted, and things are still not working, now we'll need to narrow down what is and isn't working for you. Here are the things to try installing/updating:

1. Platform app store load (note that if this fails for you, no need to attempt the others... and you should check to ensure your platform's Connection is set right in Options. The default is automatic)
2. FirefoxPortable (SourceForge hosted with PA.c redirect)
3. 4stAttackPortable (SourceForge hosted without PA.c redirect)
4. AIMP (PA.c hosted freeware, old style redirect)
5. Balabolka (PA.c hosted freeware, new style redirect)
6. Inkscape (Publisher hosted)

Make a note of what does and does not work. Now, for any that do not work, please try launching Internet Explorer, visiting the PA.c site, and downloading these apps. Please note that ONLY Internet Explorer matters for this test as it uses the Windows networking components. It does not matter if you can download in Chrome, Edge, Firefox, etc so please do not report back about those.

Now, please post a comment with what is and isn't working for you along with the following details about your setup:

1. Platform version and whether it was a fresh install or upgrade
2. Connection setting in platform options (default is Automatic)
3. Windows version and bit depth
4. Full install path to the platform's Start.exe file

Once we're at this point, I'll try to recreate your issue on a clean virtual machine install of your exact setup of Windows running from the same path. Hopefully I can reproduce it and work on a specific fix for your specific cause.

In addition to the above, I'm working on an alternate download method for the platform, likely using curl in the short term. It will allow us to bypass the Windows networking components and add SOCKS proxy support, but it won't let us show download progress within the Platform's interface. We may be able to show progress in a command line window for advanced users.

My apologies for the complexities of this post and my thanks for working through this issue so we can ensure we get downloads working everyone.

Unable to Update Details


I'm having update problems, too. Before going into the details, I have to say THANK YOU! PortableApps is the BEST! Now, on to the facts.

This is for Windows Vista (I'll join you in laughing, but please keep it to a minimum so we can move on! I know it's outdated & unsupported, and was pretty lousy to begin with, but I have a goal for this old clunker, and will reach it next month - 10 years with one OS, even if is a bad one. That's over 222 MILLION seconds of power on time [7+ years] and a 470,000+ load/unload count.!)

As for the download errors, I believe all the requested info is here, but I did sneak in a couple of irrelevant notes on Chrome downloads.

### Notes ###

- FirefoxPortable downloads and installs, but doesn't start - no error message. (No Vista, perhaps?)
- Previously able to update PortableApps on the local drive, external drives, and USB drives.
- Apps have been updated every few weeks with only the occassional temporary glitch.

That's all, folks! Hope this helps for those of us (a small minority of users, I suspect) having trouble with updates.

Issue Determined, Fix Coming, Manual Patch Details

I've discovered the reason for the specific issue you are encountering. Vista, like XP, is discontinued and only supports less secure https connection methods (TLS 1.0 and under), which are considered insecure by many. As such, many web servers have been updated to TLS 1.1 and higher and to reject other encryption cyphers. Inkscape's server and several SourceForge mirrors now fall into that group. That's why you can't download via the platform and why it fails in Internet Explorer on Windows Vista (and XP).

I'm working on a fix for those users to fall back to our servers for those downloads in the next few days.

Also, you can update Vista using an unofficial process to enable TLS 1.1 and 1.2 support. Some Windows 2008 Server patches will work on Windows Vista. One such patch is for KB4019276. The process is detailed in this article. First you visit this download page. On that page download Update for Windows Server 2008 (KB4019276) 11/10/2017 if you have Vista 32-bit or Update for Windows Server 2008 for x64-based Systems (KB4019276) 11/10/2017 if you have Vista 64-bit. In the popup window, click to download the MSU file linked. Once downloaded, run the file, apply the patch, and click to restart when prompted. After rebooting, download and apply this .reg file (right-click to download) to remove the two values mentioned in the above article. Then open up Internet Options, go to the Advanced tab, and enable TLS 1.1 and 1.2. This will allow you to use these cyphers in Internet Explorer, apps with embedded browsers, and apps that use Windows internet components like the Platform. Note that this process could be a licensing violation in your region.

Sometimes, the impossible can become possible, if you're awesome!

Manual Patch Installed

Thanks, John, for the incredibly quick reply and suggestions. I followed the tutorial above, installing the Server2008 update KB4019276-x86, and after backing up the registry, I added the new registry entries.
The good: Basically, it worked.
The bad: The laptop KB4019276 was installed on, with continuous uptime of exactly 30 days without incident before the install reboot, and 4 months without a crash, has now had the dreaded BSOD blue screen crashes 6 times in 20 hours, with this error:
(Note: Details are from Crash #1. Bug Check String & Bug Check Code are the same for all 6 crashes.)

I suspect the crashes are related to the system changes, but in fairness, I am knowingly running a failing hard drive (62K hrs) which will be replaced soon (hopefully with Windows 7), and the reboot may have triggered some problems, although the HDD stats/alerts have not changed.

Also, Windows Update History and uninstallers do not show the standalone install of KB4019276-x86. I'd like to figure out how to uninstall it before having to do a full restore. I have separate registry backups, but didn't save a System Restore point, which I've had sporadic success with in the past. Sometimes it works, just as often it does not.

Internet Options have not changed other than TLS 1.1 & 1.2 being added, as expected.

[ ] Use SSL 2.0
[ ] Use SSL 3.0
[x] Use TLS 1.0
[x] Use TLS 1.1
[x] Use TLS 1.2

With Vista running, PortableApps now runs update checks and updates/installs normally on the local drive, external drives, and USB sticks.

Next, I downloaded all eight browsers available via the PortableApps Platform. All of them install normally, but only two, K-Meleon & Maxthon Cloud, will run on Vista. (They're not among my preferred browsers, but at least it's an option.) Also, while Chrome is no longer supported in XP or Vista, I'm puzzled as to why FirefoxPortable won't run, unless it doesn't support the ESR (Extended Support Release) channel. Firefox 52.7.3 (32-bit) ESR does run in Vista, albeit slowly.

Browser Test Results:

[ Fail ] Chrome
Error Title: chrome.exe - Entry Point Not Found
Error Msg: The procedure entry point TryAcquireSRWLockExclusive could not be located in the dynamic link library KERNEL32.dll.

[ Fail ] Iron
Splash Screen shows, timer appears briefly, never opens. (Identical to Mozilla Firefox.)

[ ok ] K-Meleon
This browser works in Vista.

[ ok ] Maxthon Cloud
This browser works in Vista, too.

[ Fail ] Mozilla Firefox
Firefox/PortableApps Splash Screen shows, timer appears briefly, never opens.

[ n/a ] Opera
Opera displays an informational message that Windows 7 or later is required.

[ Fail ] Private Browsing by PortableApps
Splash Screen shows, timer appears briefly, never opens. (Identical to Mozilla Firefox.)

[ Fail ] QupZilla
Splash Screen shows, timer appears briefly, never opens. (Identical to Mozilla Firefox.)

And that's where it stands after a weekend of trial and error testing.

Firefox ESR

You have to manually select the Firefox ESR channel which is hidden by default. Open platform options, select advanced, and enable advanced apps to gain access. The main Firefox stable channel dropped XP/Vista with the release of Firefox 53. Firefox ESR will drop XP/Vista later this year. None of the browsers you had issues with support Vista any longer. Please note that this is outside the realm of this specific topic as we're only trying to determine why specific users can't update.

As to the crashes, I'm unsure what could be causing those and if it could be due to the patch. I know that the site I'd linked lists some of the patches that will apply to Vista and help make it more secure but that it is hit and miss which of the Server 2008 patches will even apply. It's completely unsupported, as is Vista at this point. It should, in theory, show in the list of applied patches. It may be possible to re-apply Vista Service Pack 2 to restore the original files rather than doing a full restore from an earlier backup, but I do not know. This is uncharted territory for me (and unsupported by everyone) and a bit beyond the purview of supporting our software. In my brief testing on a clean Windows Vista in a virtual machine it did work successfully and did not cause any crashes. It does properly show in the list of updates and I was able to successfully uninstall it without issue. Once uninstalled, the expected behavior of downloads from us working by downloads from sourceforge not returned, so it appears the uninstall was successful. You should also be able to uninstall the update from a command line run as administrator with: wusa /uninstall /KB:4019276

Sometimes, the impossible can become possible, if you're awesome!
