[wpkg-users] How to handle unknown uninstaller name?

[Robin Roevens]

I have expierienced that applications like Gimp, PDFCreator, and others 
indeed start using uninsXXX files with XXX != 000 when removed and/or 
reinstalled.. 
Most of the time this gives me multiple uninsXXX.exe files, but only one 
valid uninsXXX.dat file making that executing any uninsXXX command that 
hasn't the same number XXX as the only uninsXXX.dat file results in a 
dialog box with an error, which doesn't dissapear from itself, hence 
blocking further wpkg processing (or waiting for a wpkg timeout). Hence 
making the FOR method invalid in this case...

I myself solve this quite simple by adding a few remove commands like 
this:
<remove cmd='%comspec% /c if exist "%ProgramFiles%\Gimp\unins000.dat" 
"%ProgramFiles%\Gimp\unins000.exe" /verysilent /norestart' />
<remove cmd='%comspec% /c if exist "%ProgramFiles%\Gimp\unins001.dat" 
"%ProgramFiles%\Gimp\unins001.exe" /verysilent /norestart' />
<remove cmd='%comspec% /c if exist "%ProgramFiles%\Gimp\unins002.dat" 
"%ProgramFiles%\Gimp\unins002.exe" /verysilent /norestart' />
