Hello, tell me what to do when when trying to update the driver 474.14 at the very installation of the driver gives an error : Access to the path "DisplayDriverExt.dll" is prohibited.

hmm .. this happens every time? A reboot doesn't make a difference?

You get this error after all the steps, when you click the "install" button at the end?

NVCleanstall has worked before on this machine?

I just got this error myself. Only after finishing the install for version 536.67 and trying to close NVCleanstall_1.16.0.exe

The installation looks fine, but not sure what other issue I might encounter....
 
I had it once, too, but couldn't repro it on a 2nd run

Then I guess it should be fine. if I see it ever again I will let you know. Thanks!
 
Just updated to latest nvidia driver and NVCleanstall (1.16) raised this error (never seen before).

I wonder if its a timing issue from outside?

Decompression
AV Scan
IO wait from drive
FS busy


Race condition? Maybe need an artifical wait before next process?
 
Maybe.
It did happened at the very end of the install.
Earlier installs worked without a problem.
 
Race condition?
Yeah access denied usually suggest a timing issue/race condition. But when it's hard to reproduce, it's hard to fix, because I can't investigate/test
