Just as it says Never had a Problem before been playing for years. it loads all the way then wont light up the play button. so i cleaned out cache re downloade the Gamme Launcher no change. shut it down for a few hours went back to try now i have this error Code.

I tried to ReInstall about 5x no change. Out of no where got a pop up from gaijin wanting to make changes to my computer i clicked yes and it fixed the problem Thanks if Ya’ll had something to do with it. Fixed now can be closed
Please, attach log file of launcher.
See it in game folder, subfolder named as .launcher_log

Logs have ho traces of any setup executable being launched.
From the error message I can assume that there isn’t enough space in system Temp folder or something prevents you from writing to this location when the setup executable tries to extract its temporary files.
A tip even if it isnt the problem, check the local user temp folder as there is usually a lot of crap in there. I find old camtasia files that take up gigabytes among other useless files 
Ok Thanks. Ya It works fine now after the pop up to fix.
