Hello,

I had a very similar problem today, and it took me a while to find an elegant solution. My application had the following UninstallString, with 'SOME GUID' being a different guid every time:

"C:\Program Files (x86)\InstallShield Installation Information\{SOME-GUID}\setup.exe" -runfromtemp -l0x0009 -removeonly

I managed to uninstall the whole thing in 3 CMD lines

FOR /F "tokens=*" %%A IN ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall /f "UNIQUE_DISPLAY_NAME" /s ^| FindStr /R "[{].*[}]"') DO SET GUID=%%A
set GUID=%GUID:HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\=%
"%ProgramFiles(x86)%\InstallShield Installation Information\%GUID%\setup.exe" -runfromtemp -l0x0009 -removeonly -s -f1"c:\complete\path\to\uninstall.iss"

So what this does, is search the part of the registry where the uninstallstrings are for the 'Display Name' (This name needs to be modified). The line that contains the GUID is then filtered out by searching for a regular expression with FindStr /R "[{].*[}]". The result is stored in variable GUID.

After the first line, the variable GUID should contain: 

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{AND-THE-ENTIRE-GUID}

The whole path is then deleted by a search and replace, with a syntax I only discoverd today, for example, to replace 'teh' with 'the': VARIALBE = %VARIALBE:teh=the%. What remains is the GUID.

I then generated an uninstall.iss using the -r switch, and included it as a parameter with: -s -f1"c:\complete\path\to\uninstall.iss" (don't forget to include the full path if you do this, otherwise you may have unexpected results).

Hopefully, this will help someone, someday.

Cheers!
