So, you use iWin Games (Cake Mania, Diner Dash, etc.) and your Games Manager crashes upon startup? More than likely, the error you receive is that C:Program FilesiWin GamesAdminWorker.exe cannot be found. This is how to reinstall Games Manager (without losing your games or purchases) and why that occurred.
Some anti-virus applications show iWin Games (AdminWorker.exe, GLauncher.exe, etc.) as a virus (or Trojan, specifically). When you see the warning from your anti-virus about a suspicious file, odds are that you’re just going to Quarantine or Delete the “threat.” The problem is, as stated, integral parts of iWin Games show as viruses, so you may have just quarantined or deleted a file that’s needed to play your games.
If you quarantined the file, you can go into your antivirus and remove the file from quarantine. I’d also suggest showing the file as safe with your antivirus.
If you deleted the file, simply uninstall iWin Games (not a specific game, but the program labelled, “iWin Games”). Follow this guide to uninstall without removing your games, preferences, or purchases: How can I reinstall the iWin Games Manager? If the link does not work (iWin may have disabled hotlinking to articles), then you can visit the support page and search for, “reinstall.” http://support.iwin.com/ics/support/default.asp?deptID=5419
I strongly suggest that, if your antivirus again detects c:Program FilesiWin GamesAdminWorker.exe or another iWin program as a virus/Trojan, to mark the file as safe to avoid this in the future. More information: http://support.iwin.com/ics/support/KBAnswer.asp?questionID=31
