1) Completely shut-down and exit Steam.

2) Go to...

C:\Program Files (x86)\Steam\appcache\appinfo.vdf

3) Delete the file appinfo.vdf

4) Re-start Steam and try again.

Can anyone confirm that this works and probably won't cause my computer to explode?

Hello! I've recently bought the game Stellaris through steam, but a while back I purchased the DLC for the game through Microsoft. I've been trying to download the DLC, but It keeps telling me I need to install the game. I have the game installed already. Can anyone help me?

I would confirm the DLC from Microsoft works with the Steam version of the game. Then I would search the internet for exactly what you want to fix, gradually widening the net until you find something helpful. I would expect basic troubleshooting could include things like; try to verify the game files, uninstall/reinstall the game, restart your computer, disable 3rd party antivirus, and all the other usual stuff we always do to troubleshoot something like this.

Certain games/DLC's require third-party launchers to be 'activated', so that's why you might get that error.

I am assuming that this is the case for Cities Skyline, since it's from Paradox.

Just an FYI for future readers: deleting appinfo.vdf will assist only if that file is corrupt.

I should've mentioned that in 2018 when i posted it.
