I cannot seem to uninstall the isscript8.msi using:

msiexec /x {790EC520-CCCC-4810-A0FE-061633204CE4} /qb-

as i usually do. It gives the error:

This action is only valid for products that are currently installed. Im pretty sure this is the GUID, is there another trick to make the InstallScript engine uninstallable from a command line?

If you have the MSI file handy, MSIEXEC /x ISScript.msi /qb-

Maybe it's a different release of ISScript8? The version needs to be an exact match for that command line to work. Look through the Windows Installer regkey.

On reviewing the installer area in the registry it appears that the InstallShield Scripting Runtime does not make an entry in this table, nor does it make an entry in the uninstall table. I tried it using msiexec /x isscript8.msi and got the same error. maybe this app cannot be removed conventionally

Just for reference, I could not uninstall ISScript8.msi either.

I would check the Installshield support forums for an answer to this. It's obvious that ISS is installed to stay for the life of the workstation, which is a shame.

Your other option is to take the vendor msi and make a copy of it. Change the Product code and then set all components to be removed on install in order to clear it from the system. I have done this in the past ro remove badly packaged apps.
