Google finds me someone saying they copied steamservice.dll manually Same, lots of ERROR: SteamService: Failed to get version of existing DLL and kicked out of vac server games. So, I delete everything, the steam in common files, all the files in c:\steam and reinstall steam.Īdd my steam libraries from the other disks and, nope. The odd thing is steamservice.exe is in c:\program files(x86)\common files\steam not in c:\steam I presumed (correctly) this was the actual error and not the 'vac is blocked' - (Valve please hire some developers with a clue) The log was full of "ERROR: SteamService: Failed to get version of existing DLL" messages. I the support page it links to is next to useless (a thinly veiled valve telling you you are running software to try and block it)Īnyway, I eventually found someone saying to start steamservice or 'steam client service' in services. Then I started getting disconnected from servers with vac is blocked. I kept steamapps on a couple of existing drives.


Once restarted, it would immediately exit with an error 1051, but the vulnerability would still have been exploited."īut, I have no idea if there's actually anything wrong being reported in that Event Viewer warning or if it's just a side-effect.įWIW, just reinstalled windows on a new ssd. "Liu discovered though that he could exploit the vulnerability again by simply replacing the C:\Program Files (x86)\Steam\bin\SteamService.exe and C:\Program Files (x86)\Steam\bin\SteamService.dll files with older vulnerable versions and restarting the "Steam Client Service".

It does look like this is part of the security issue: They appear to be the same size and version (though the SteamService.dll one on the C: drive has a newer modified date). Should I delete that entire C:\Program Files (x86)\Common Files\Steam folder or leave things be? I haven't been able to find anything useful on the net.ĮDIT 1: I've also got copies of those two files under the /bin folder where Steam is actually installed (D and E :\Steam\bin). I've scanned these machines with 4 different anti-virus scanners and they're both clean. Looking in that folder, there exist SteamService.dll and SteamService.exe. Yet the warning shows the file as being in C:\Program Files (x86)\Common Files\Steam. Oddly, in both our cases, we have Steam installed in non-standard locations (D: and E: drives). Same problem here on both our machines starting on.
