MSFS 2020 uninstalled itself

Featured Replies

So I re-installed 2020 to work alongside 2024, mainly to keep flying the Max 8. I had it working well, did a flight this morning with it. I was using 2024 while i installed some other previous addons into 2020 and noticed the entire sim has been uninstalled! Is this a thing that will keep happening?

2024 has nothing to with 2020 - you might as well have been playing Cyberpunk or some other game.. The two aren't related and installing/uninstalling one has no effect on the other one, just as it wouldn't affect a random game. 

As to why your 2020 installed vanished..

1. Did you do a Check File Integrity (or something like that) in Steam?

2. Perhaps an installer for the addons accidentally wiped the directory?
 

Do you have some sort of file checker/cleaner running in Windows?

It's not via steam, and i was just installing the wbsim 172. I don't see how that would remove an entire sim.

 

I'm reinstalling it again, will see what happens. Thanks for the ideas though.

Are you using xbox for pc to install/uninstall? The xbox app will relocate critical folders for 2020 when you install 2024. You can actually move the folders simply by changing the install location in xbox settings. A gotcha is if you install 2024 after 2020 then uninstall 2024 your 2020 will not work. You have to go into Xbox install settings and change the install location to match your 2020 install. Very strange behaviour. I’ll add that I have 2020 and 2024 installed on a single 2TB NVME drive in folders called W:\MSFS and W:\MSFS2024. The folder that keeps moving is Microsoft Flight Simulator with content etc.

I have FS2020 working very well in a custom location on its own 2tb NVMe and it is these sort of threads that make me very cautious about installing FS2024 - it all sounds like a recipe for disaster if you want to keep FS2020.  If I install FS2024 I want it to be on its own 2tb NVMe.

That's why I gave up on FS 2020...

A sim that uninstalls itself? What pleasure would I get from it?

Nah, not for me!

I uninstalled 2020 when 2024 came out. 2024 obviously had/has it's issues but I persisted with it. I still enjoy it and plan to use that most of the time, I only installed 2020 again 2 days ago because I missed flying the Max 8. The entire time I had 2020 in the first place I never had that issue. I'm not saying 2024 had anything at all to do with it. I've been at work so haven't had a chance to test it again, but will see how it goes.

That is ridiculous, one person has a problem with 2020 uninstalling itself, so you think that is  an issue with 2020.?

Think you missed the sarcasm, as he is constantly installing and uninstalling Sims on purpose. No need for one that does it all by itself 😅

C'mon Bob, give me a break... Can't you glimpse the sarcasm?

I had the same issue once. I uninstalled FS24 and it took MSFS right with it.
