why do my games self uninstall ????????? LOTS OF FUN!!!!!!!!!!!!!!!!

Things don't just self uninstall. But if you are asking for help figuring it out (which isn't clear) you could provide a little context. You know, what games, if you're using Galaxy, stuff like that.

Do they fully self-uninstall (including deleting savegames), or does the .exe disappear? Some antivirus programs are known to sometimes delete the .exe file of installed games because of false positives (Avast is a known offender). Adding an exception to the folder where your games are installed should do the trick.

Games on Galaxy, Like The Surge , Lords of The Fallen , Elex

Your AV might be quarantining/deleting the executable or some other crucial file(s) when you try to run the game -- though if a bunch of different games seem to be "uninstalling", the problem likely lies elsewhere. But as firstpastthepost said, you need to give more info if you'd like anyone to be able to help.

EDIT: Just saw your last post; probably not your AV interfering, then. Maybe try installing one of them via the standalone "backup" installer, see if that makes a difference?

The game seems to be there just want run. Galaxy says uninstalled.

I don't use Galaxy so I'm not sure if this will actually work... but if you browse to the games directory on your computer I assume there is an executable file there, can you run that?

Try running one of the installed games from the .exe file, then.

Thanks I'll try that. Thanks I'll try that.

Sometimes Galaxy bugs out and causes your installed games not to appear in the list that it shows.

You can fix that problem by telling Galaxy to re-scan the folder where your Galaxy games are installed. After you do that, then the installed games will be listed there on Galaxy again, just as they were before.

That is presuming your problem is the same one which I'm thinking of, which I'm not sure if it is or not.

Antivirus - yea, make sure Galaxy and the games are in the antivirus and windows defender exceptions list.
Also I am wondering if the OP used a program like 'CCleaner' and cleaned up the registry?

Any luck?

Yes, rescanning typically fixes that problem.

I have a running install now, let's see how long it last. Thanks for your help and input.

Glad to hear it. :)
