AppV (App-V) management console begins crashing post startup, after selecting an individual package/software (for example: Photoshop.) Type of error is a runtime exception and no matter what you do, seems unable to be fixed. Re-installing has been reported to work (why it works is related to the fix) but the issue re-appears soon after that.
System & Version:
Windows 7 (x64) - All Versions
AppV Management Server 4.5 SP1 - Management Console specifically.
Note: Client is 4.6 SP1 and this should work for all 64-bit versions of Windows, might be in a slightly different registry address for WinXP x64
Its because your system has more than 2GB of RAM (as far as we can tell) and specifically a 64-bit version of Windows. Microsoft has no fix yet. Crashing begins to occur after it has cached more than 500~2,000 icons.
This is a fix to stop caching icons and, thus stopping the crashing. Downside: All icons are replaced with a generic AppV symbol.
Open up a CMD Prompt / Console as Administrator and execute this (x64 fix only):
REG ADD "HKLM\Software\Wow6432Node\Microsoft\SoftGrid\4.5\Management Console" /v LoadConsoleIcons /d 0 /t REG_DWORD /f
