Hi all,

I'm trying to create a batch file that uninstalls a product before rolling out its new version. However the product (groupwise) when its installed creates itself in the registry as a random key in currentversion\uninstall section of the registry so I cannot simply do a reg query "blah/blah/groupwise uninstallstring"

Does anyone know of the right way I should be doing this by either searching all the keys in uninstall checking for groupwise and then retrieving the uninstallstring, or is there another tool i can use to do this task (the tool has to be referenced by all computers so it can find the random key).

After I can retrieve the key I can set it as a variable and instigate the uninstall routine.

Not sure if this is really what you want but you could try this. I am not sure if it works I have just come across it in my office it will update the code in the registry for a product

You can get the upgrade code of an existing application by enabling Windows Installer logging and running a Repair of that application from Control Panel.


1. Load the registry key file
2. Clear our your Local Settings\Temp folder
3. Run a Repair from Add/Remove Programs in Control Panel
4. Look for a log file in the Temp folder. It will have a random filename
5. Look for a line that says "UpgradeCode =" - this will be your upgrade code

 

Hopefully this is the correct "groupwise", if so this may help
