Yo, if you've been chilling with SteamTools for your games and suddenly everything throws a "Purchase Error" or "No licenses" message when you try to launch... yeah, same boat here. Hit me right after the latest Steam client update rolled out a few days back. Games that were running smooth just vanish from the playable list or refuse to start. Super frustrating, especially when you're in the mood to hop on.
Good news: most folks (including me) got it sorted with one simple trick that forces Steam to refresh its license/cache stuff. It takes like 3 minutes tops. But heads up—this will wipe your local achievement progress on those games because it nukes some cache files Steam uses to track that junk. So do this first if you care about your unlocks:
- Grab Steam Achievement Manager (SAM) real quick—it's free on GitHub, super lightweight.
- Fire it up, back up your achievements for the games you're fixing (just select and save/export).
- You can re-import them later once things are back online.
The Actual Fix Steps (Super Straightforward):
Shut Steam down completely. Like, fully—right-click the tray icon > Exit, then double-check in Task Manager (Ctrl+Shift+Esc) that no Steam.exe or related processes are sneaking around.
Open File Explorer and head to your Steam folder. Default spot is usually: C:\Program Files (x86)\Steam
Go inside the appcache folder.
Look for these two files:
- appinfo.vdf
- packageinfo.vdf
(If they're not there, no biggie—just move on.)
Select both (or whichever exist), right-click > Delete. Or drag them to your desktop as a backup if you're paranoid (Steam will just make new clean ones anyway).
Restart Steam. It'll take a sec longer the first time because it's rebuilding those files fresh from the servers.
Open your game via SteamTools like normal.
Didn't click right away? Try this bonus step:
- In Steam, click Steam (top left) > Settings > Downloads
- Hit Clear Download Cache
- Let it restart Steam, log back in, and test again.
Why does this even work? Basically, Steam keeps a local copy of app and package/license info in those .vdf files. When Valve pushes an update, sometimes the old cached data gets out of sync with their servers → instant "no license" or forces a fake purchase prompt. Deleting them is like hitting the refresh button; Steam redownloads the correct info and boom, games launch again.
What people are saying after trying it:
- "Deleted those two files, restarted, and everything popped back like magic."
- "Achievements were gone but SAM saved me—worth it."
- "Had to clear the download cache too, but now it's solid."
If it still acts up after this, give it a day or two—sometimes SteamTools needs a tiny update on their end to match whatever Valve changed. But 9/10 times, this does the job.
Hope this gets you back in the game fast! If it worked for you, shoot a quick "worked" in the comments or pass it to a friend who's stuck. Happy gaming, legends. 🎮
