iRacing: Fix This Damn Steaam Update Files (Workarounds)
Short answer
No confirmed fix yet. Players suggest: Don't update with steam.

every f time u guys releases a update i simple need to unistall the whole 170gb game and install it all the way. Why ? cause this damn game cannot update normally anymore, it brokes at 80/90% while installing every time with a diferent type of error.
What players suggest
Don't update with steam. When iRacing shows in your steam library that there is an update, launch iRacings UI from your install directory, do not click update on steam. The UI will update iRacing, close UI once done. Click update on steam and steam will then see iRacing is actually up to date and will just launch iRacing.
Then you will have to start iRacings UI from your install directory to finish the update. Then go back to steam and hit update again and it will see that it was already done by iRacing and launch iRacing. The next time you have an update for iRacing, use the iRacing UI to update instead if steam. Alternatively, you can contact iRacing to have your account moved off steam. The process takes less…
DONT KNOW IF YOU ALL ARE STILL HAVING THIS ISSUE... As this is the first time in a year that i have come across this issue... Looking it up on iracing's site, it tells you to end the "IRACING HELPER SERVICE" in your TASK MANAGER and then try to finish update... Seem to work for me, hope this helps others who may come across this issue…
