At least this worked for me, with the complete collection, I found it here- https://www.🐸🐸🐸🐸.club/t22742-the-sims-1-installation-unknown-error-encountered-aborting-setup#


When you attempt to (re-)install "The Sims 1" from 🐸🐸🐸🐸, the installer might not come up at all, or you may be confronted with the error message that is in the topic title of this thread ("unknown error encountered - aborting setup").

The error seems to be caused by a previous (faulty) installation of the game. What you should do now is this.

1. Make sure to unhide all hidden files/folders. In Windows 8 & 10, you should be able to mark the option "hidden items", shown in the screenshot here.

In Windows Vista and 7 go to the Control Panel -> Appearance and Personalization -> Show hidden files and folders. Under the tab "View", scroll down a bit and tick the option named "Show hidden files, folders and drives". Click on Apply, then OK.

2. Navigate to the location C:\Program files (x86). You should see a folder named "InstallShield Installation Information". Go inside it.

3. In my case, there was an entry for The Sims 1, with the folder name {F2527115-B8BF-4FDB-B5DA-5AADFB7C13E1}. If you see such a folder in your case, delete it, and try the installation again. Pay close attention to the folder name, so that you don't delete anything wrong ! If you don't have such a folder, you should check all other existing folders instead, under InstallShield Installation Information. Navigate inside each subfolder and open the "Setup.ini" files. Keep looking under "AppName" until you find the folder that contains "The Sims Complete" under AppName. And that is the folder you will need to delete.
