[Fixed] Redirection (302) error when updating apps hosted on SourceForge

Likely, you have a software firewall or something else installed locally that is interfering with the redirects. The PortableApps.com Platform's updater uses Windows' own internet components to handle the download. It says "hey Windows, download this exact file please", then Windows does the download and passes back whether it works or not. That Redirection (302) error is being passed to us by Windows to say that it couldn't handle a common redirect for some reason. The only time I've seen this happen when there wasn't a major SourceForge configuration going on is when a local software firewall or antivirus has messed things up a bit.

I can assist more if you tell me one specific app (app name and version) you are downloading and experiencing the error on as well as your Windows version and what antivirus, antimalware, and firewall you are using.

I've started running into this problem as well, running an update this morning.

The following applications appear to have updated successfully:

CPU-Z
DSynchronize
Foxit Reader
GPU-Z
LibreOffice
Skype

The following applications failed to update:

7-Zip
CrystalDiskInfo
CrystalDiskMark
DVDStyler
FileZilla
Google Chrome
Kaspersky TDSSKiller
Mozilla Firefox
Mozilla Thunderbird
Notepad++
Stellarium

The error dump window afterward indicated the following files as having Redirection (302) errors:

(Runs off the edge of the window at this point.)

I will attempt to perform the update on an open network solely with the default Windows firewall shortly to see if the problem is consistent.

Attempting update while on an unmanaged network with only default the Windows firewall, and antivirus (Kaspersky) completely disabled, exhibited the exact same result.

For grins, I attempted to update a thumb drive that had not yet been upgraded to PortableApps 14.2.
The update failed due to Redirection (302) error.
http://downloads.sourceforge.net/portableapps/PortableApps.com_Platform_...

I downloaded the installer manually to perform the platform upgrade. This worked fine.

Once that was done, the following applications were in need of updates:

7-Zip *
CPU-Z
CrystalDiskInfo *
CrystalDiskMark *
DSynchronize
DVDStyler *
FileZilla *
Foxit Reader
Google Chrome *
gPodder *
GPU-Z
Kaspersky TDSSKiller *
LibreOffice
Miranda IM *
Mozilla Firefox *
Mozilla Thunderbird *
Notepad++ *
Skype
Stellarium *
uTorrent *
Warzone *

Items marked with asterisks failed to update. So, it's consistent in what's working and what isn't.

Wondering if Sourceforge changed something on their end?

Just took the same thumb drive and dropped it into a fully-patched Windows 10 system. (Had been doing all of this on a fully-patched Windows 7 system.) Configurations otherwise nearly identical. Lo and behold, it works fine there. Hmmm.

Yup, same problem. First time I've ever seen it, and it started around Christmas. No major changes on my Win7(64b) system.

Here is a link to the screengrab of the error.

This issue is caused by setting Windows to alert you on crossing zones (HTTPS to HTTP). Go to Windows search and enter "internet options" and click on Internet Options in the results list. In the Internet Properties dialog box, click the Advanced tab. Scroll to the bottom and uncheck the box next to "Warn if changing between secure and not secure mode". Click OK. It will work again.

This setting is not on by default and turning it on will break many apps that utilize Windows networking components. A future update to the platform will have a patch to work around this issue.

This issue is fixed in today's PortableApps.com Platform 14.3 release without needing to adjust the advanced Internet Options setting mentioned above. This will allow users to freely move among computers even on PCs with this setting changed.

I have updated the platform to the latest version (14.4.4.1) and still get the error. It STILL seems to only be an issue with files hosted on sorceforge. I have to downlaod and install them manually.
