Trying to install GPUTweak2 that ... for some reason, disappeared like CAM+.

Getting the error "1608 unable to create installdriver instance". I understand it is related to InstallShield. All my attempts failed to fix it, sfc, unreg/regserver, etc. Anyone can help out?

That's a fresh install of Win10 we're dealing with. Getting sick of this sh*t.

I don't have a specific fix, but I suspect from the message that it's probably related to something windows sees as an unsigned driver. If that's the case, I believe MS is moving in a direction that's not going to make you happy in that they're planning on doing everything in their power to prevent unsigned drivers from being installed.

Have you tried this?......

turn off driver signature enforcment for w10 - Microsoft Community

edit: NVM.... I see I'm completely off base, and assume that you've tried these steps???

Install Shield 1608 Unable to create install driver instance - Microsoft Community

Since it seems to involve installshield I still suspect it's probably related to windows not seeing it as a signed driver.
