Portable apps not launching on Windows 7 Ultimate

[G33kKahuna]

My work PC running WinXP SP3 32 bit was recently flattened out and loaded with Windows 7 Ultimate 64bit. Some of the portable apps crash on launch. I am logged in as local administrator as well. I have performed the following steps but still no luck. All programs are under "Program Files" and "Program Files (x86)" folders

1. Executed TAKEOWN /f on both directories
2. Executed ICACLS /grant administrators:F /t on both the directories
3. Set the application compatibility mode to Windows XP SP3 and even tried launching with "Run as Administrator"
4. Ran procmon when launching the applications. None of the entries stood out except a CreateFile entry prior to process exit related C:\Windows\Prefetch with result status NAME_NOT_FOUND. However I could navigate to the directory and locate the file as well
5. I tried launching in Windows XP Virtual PC and received module MSVCR80.dll cannot be loaded error message

Any help is much appreciated

Portable apps not launching sometimes is a DEP problem. Event viewer would show event ID 1000 (app crash) with source 100. usally can be cured by changing dep setting to "for all apps"

Just a guess hope it works
