I installed GIMp Portable to my 32GB OCZ ATV pen drive. I have a number of other portable apps on here, including your VideoLAN portable (not the latest - waiting for more reported stability)
Anyway, two of your apps simply won't launch, whether I call for them from PStart or go directly to them in windows explorer and double click them. The two are GIMP Portable and Celestia Portable.
Trying to launch them simply does nothing. I get a microsecond of hourglass, then nothing. They don't show up in task manager. They never launch.
Additional info: I'm trying to run them on two different WinXP Pro PCs, the USB stick is formatted FAT32 w/ default allocation. Every other portable app launches fine (I have about 10 other apps on it).
Side note: Celestia will launch if I bypass your CelestiaPortable.exe wrapper launcher, and go directly to Celestia.exe. I haven't tried it with GIMP. At any rate, I figure launching them directly will result in leaving info on the host PC, and I don't want to do that.
Any ideas? Thanks for any help.
