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 22.214.171.1249 (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.
