[STEAM (CS GO) - VAC Authentication Error caused by CCleaner]

Unfortunately, excluding the STEAM folder does not work.

 

Ran CCleaner earlier, started a ranked match and was kicked out / banned after 7 rounds.

If you use a downloaded winapp2.ini community file, or one from CCEnhancer look in that winapp2.ini file and remove everything that would clean Steam - or remove the winapp2.ini altogether.

 

How to make CCleaner exclude Steam:

1. Start CCleaner.

2. Go into: Options > Exclude

3. Input all of the paths to Steam (physical folders or files, and registry paths).

CCleaner will now skip Steam.

Thanks - will give it a go.

 

Somehow completely missed the exclude tab.

[STEAM (CS GO) - VAC Authentication Error caused by CCleaner]

Hey guys,

 

Been using CCleaner for years, but it seems that either an update from Valve's end or CCleaner has caused problems.

Everytime I run CCleaner now - the next time I play a match of CS GO - I'll get 'VAC Authentication Error' and be unable to reconnect resulting in a ban.

 

This is with 'Steam' de-selected in the application options before running CCleaner.

 

It took a while to find the cause of the issue but it seems to be a common problem:

Is there anyway we can strictly stop CCleaner from touching CS GO / Steam files?

 

Thanks!
