[wpkg-users] InnoSetup, uninsXXX.exe and "uninsXXX.dat is corrupted"

InnoSetup apparently doesn't overwrite uninst*.* files when 
upgrading, but increases filename.
Therefore I handle InnoSetup uninstallers by removing old uninst*.* 
files when upgrading:

<upgrade  cmd='%COMSPEC% /C if exist 
"%PROGRAMFILES(X86)%\AppInstalledByInnoSetup\unins*.*" del 
"%PROGRAMFILES(X86)%\AppInstalledByInnoSetup\unins*.*" /Q /F' />

InnoSetup will create them new (naming them uninst000.* ) when 
upgrading.

To be on the safe side, I'll check for uninstaller file names when 
removing:

<remove cmd='%COMSPEC% /C if exist 
"%PROGRAMFILES%\AppInstalledByInnoSetup\unins000.exe" 
"%PROGRAMFILES%\AppInstalledByInnoSetup\unins000.exe" /VERYSILENT 
/NORESTART /SUPPRESSMSGBOXES />

Hope this helps
