Game client will not patch

[Cryotic.8452]

"An unexpected error was encountered during patching. Please try again. If the problem persists. please contact customer support. 6"

 

I have seen the ArenaNet post about Lavasoft. I have anti virus client Avast.

Disabling Avast has no success.

Running GW2 as administrator has no success.

 

EDIT: I have found the issue. My disk was full. Athough I should have seen this myself, most programs when installing/updating warn about this and it might be an added benefit to have the GW2 client check and alert on this.
