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

[Paul McGrath]

Innosetup usually does overwrite the unins000.exe but there are the occasional blips, often user related through testing or sometimes a poorly compiled setup program.  I agree with Ulli that the best approach is to uninstall and delete the whole program folder and then upgrade.  I handle it like this:

     <install cmd='%SOFTWARE%\Dropbox\Dropbox.%version%.exe /verysilent' />
     <upgrade include="remove" />
     <upgrade include="install" />
    <remove architecture="x86" cmd='"%PROGRAMFILES%\dropbox\unins000.exe" /verysilent' ><exit code="any" /></remove>
     <remove architecture="x86" cmd='cmd /c rmdir /q /s "%PROGRAMFILES%\dropbox"' ><exit code="any" /></remove>
     <remove architecture="x64" cmd='"%PROGRAMFILES(x86)%\dropbox\unins000.exe" /verysilent' ><exit code="any" /></remove>
     <remove architecture="x64" cmd='cmd /c rmdir /q /s "%PROGRAMFILES(x86)%\dropbox"' ><exit code="any" /></remove>

So the upgrade uninstalls, deletes the program folder and then reinstalls.  Nice and tidy
Paul

Hi there,

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
