Games still installed on comp just can't play

Windows yes, but if i uninstall this way wouldn't it delete the save files as well? I usually use Revo Uninstaller to uninstall program, but it's so good at cleaning that i'm worried about the saves.....

Uninstalling through the control panel just sends a request to Steam, to delete the game and clean the registry (so the game doesn't stay in "control panel"), so I would assume that it wouldn't do anything, because Steam thinks that games is already uninstalled (or will just clear the registry, so it isn't listed on remove program list).

Everything is greyed on properties. But after i tried launching Thief the first time the error appeared and before restarting Steam I verified the game file, they all validated succesfully, but once i restarted Steam i could only install it.

If i try to launch the .exe files from both games it opens the steam window to install games....

The weird thing being it happens to both games on the same day.... Today Payday update wasn't updating, i didn't pay much attention to it, being payday2.

Check the payday 2 folder, it shouldn't be that large (it should be something around 17GB).

Yeah, i cleared enough space on the HD to relaunch the install ( i didn't delete anything), it started like usual allocating space for the game, but after a short while it was " Recovering Thief files on computer", after 5 mins it finished and i was able to launch the game again..... Pretty weird actually, now i hope i won't have to make 80GB available just for being able to launch the recovery process for Payday :S

Yep that's what i did, just "installed" the game and everything was fine. It's just weird that it happens on 2 games in one day.

Did the game start up before? My problem was steam didn't recognize my games were installed.
If that's the same problem, hit install when it's already installed and he'll recognize the files i guess.
But if the games never started on your comp, maybe it's something with the computer? Make sure you have the minimum requirements, once it's installed, try to validate the local files, update your drivers, check if your antivirus isn't blocking the game or something.

Thanks after reading your 2 messages i just re-install Payday2 now. I backed-up the save since i know where to find it now.
Also you're right the file isn't that big, it's 18 sth GB. I don't know which file property i was looking at when i tried to see the space taken by Payday, probably the all steam folder?
Thanks a lot :)

So far that's the 2 only games i found out about and payday needs a 11.4GB update now -_-'

That might be the reason, i had a payday update this morning that wasn't downloading, so i just restarted steam once and the computer. Usually the computer restart after closing all programs, so it should've close steam before restarting but knows....
