The Sims Complete Collection

Hi, I'm new at this so if this is inappropriate please delete.

While trying to uninstall The Sims Complete Collection I was getting the error: "An installation support file could not be installed. Catastrophic failure". 

The solution that finally fixed this problem for me, without having to resort to using Revo Uninstaller, was this: 

1. Open File Explorer and check the 'Hidden items' checkbox (under the View tab).
2. Navigate to C:\Program Files (x86)\InstallShield Installation Information
3. Look for a folder named {F2527115-B8BF-4FDB-B5DA-5AADFB7C13E1}.
4. If folder isn't there, search folders for 'Setup.ini', check for mention of The Sims.
5. Select the 'setup.ilg' file ONLY in the folder and delete it.
6. Double-click the InstallShield's Setup.exe in the folder, then click Cancel and Yes, this creates a new 'setup.ilg' file.
7. You should now be able to delete The Sims Complete Collection from Start > Settings > Apps > Apps & features.

Hope this helps someone having the same problem.
