"An error occurred while installing garry's mod"

Hello. my friend is having an issue, he cannot start Garrysmod without an error popping up. I knew the game switched to a new “pipe” so we’ve tried different things.

We’ve uninstalled the game, and deleted two old garrysmod folders but we didn’t remove the backup named ‘old_garrysmod’.

After searching on Google i’ve noticed there are hardly any forums with this topics on this issue, only about 5.

Hopefully someone could shine some light on this. :slight_smile:

I did a better search for a wider range of steam games and found this. A thread with a solution. My friend is verifying it right now. Go here to check it out. http://forums.steampowered.com/forums/showthread.php?t=3056573

This apparently happens in other games too. My friend’s half-life 1 isn’t correctly installing. Could this be something server side?

He should probably reinstall steam if it is affecting a game that doesn’t even run on the same engine as Garry’s Mod

Yeah, we’ve come to that point. I’ll suggest him to do that later.
