"Unable to uninstall" error under Windows 8.1

Submitted by Freehunter on September 8, 2016 - 3:08pm

Original discussion https://portableapps.com/node/54905

If I use File Explorer to look around an app's folder and then go to the PortableApps folder the app folder remains highlighted. If I try to uninstall it runs for awhile then gives the error "Unable to Uninstall" the empty app folder remains. Selecting the app and choosing uninstall completes the removal.

Tried this on BlenderPortable and BalabolkaPortable with the same result.

Temp Folder Access

Submitted by Devo on September 7, 2016 - 12:32pm

At work they recently updated our security software (McAfee) and restricted user access to the Temp folder. Because of this it is causing pretty much all of my portable apps to not start (Notepad++, Gimp, 7-zip, etc.) throwing up an error that states "Another instance of [AppName] Portable is starting. Please wait of it to start before launching again." There are only a few apps that will run, Firefox being one of them. Has anybody else encountered this error or does anybody know of any work arounds?

[Solved] Internal compiler error #12345 (2GB Installer Limit)

Submitted by Jeff Savage on September 3, 2016 - 1:31am

I'm getting the following error:
Internal compiler error #12345: error mmapping datablock to 30661948.
Note: you may have one or two (large) stale temporary file(s) left in your temporary directory (Generally this only happens on Windows 9x).

I'm on Windows 10 so this shouldn't be an issue? I cleared my %temp% folder and it didnt help.

Running x86 apps on x64

I made a portable of Firefox that contains both the x86 app files and x64 app files. They are in separate folders, Firefox and Firefox64 respectively.

I added a menu to the installer that allows the user to select Firefox x86 and/or x64. I'm running Windows 7 x64 and if I choose to only install the x86 version, the portable doesn't launch because the Launcher is looking for the x64 version of Firefox.

How to avoid copying big files to system / folders spoofing

Submitted by geoslake on August 24, 2016 - 1:55pm

Hi guys

i have an app that relies on a huge dll (60mb) located in the "common files" folder.
I know how to create an Nsis launcher which copies this dll, but its not really an option with such big file size.
Is there an Nsis command for the launcher, that would fool the exe into thinking the dll is in the expected common folder, while being somewhere else ?

Thank you

[Fixed] PA.c Installer 3.4 won't update PAF version

Submitted by mwayne on August 20, 2016 - 10:20pm

When switching from PAF 3.0 to 3.2 I noticed it changed the version in the appinfo.ini too. Now from 3.2/3.3 to 3.4 it won't change it. But it works from 3.0 to 3.4. It's because of line 482 in the InstallerWizard.nsi. I think the installer should always keep the PAF version accordingly to the one it's packaged with. Can we change it to $1 <="3.0" or just adding the missing versions.

While reviewing the setup of DownloadURL2 in the PA.c Format document, I noted we had added DownloadKnockURL a couple revisions ago. I'm unsure what this would be used for, can someone expand on how this entry is supposed to be used?
