Acronis 2018 on Windows 11: Installation failed
Greetings, y'all.
I have a pretty new HP laptop with insane SSD and memory capacity. First commercial software I installed was Norton and the next target is Acronis TrueImage, wherein I have it installed on 2 other laptops (Windows 10 & Windows 7). I logged in to Acronis and downloaded it. Results:
- An Acronis blue dialog box just saying [Installation Failed] and inviting me to [View Details]
- When I click for the details, I get directed to a sparse web page with a link to Acronis support but. more important, the message:
Error details: The request is not supported - (What request?)
- An error box which I have snipped but only as a graphic:
Well, I recognize the .tib as the suffix of backup files. But what in blazes is the security setting that's thwarting a perfectly legitimate installation?
As I write this it occurs to me that perhaps I should have run the installation with elevated privileges but it wasn't a problem installing Norton.
Ideas, anyone?
Thanks much!

Thanks, Steve.
I marked this as a solution. Just as an interesting (IMHO) addendum:
Before I tried to install ATI I had also tried to install IOBit-Unlocker and encountered a similar "Incompatible driver" error. Unfortunately, I did not understand the nature of the problem. Then, upon encountering the clearer message with ATI, I took the advice and shut off Core Isolation. This allowed me to install ATI as well as IOBit-Unlocker.
And then I was unable to turn Core Isolation back on; the incompatible driver was still there. Your solution taught me that tib.sys was not necessary to the ATI application. I renamed tib.~sys and restarted.
Interestingly enough, for IOBit-Unlocker, the Core Isolation is still a compatibility problem, only now it's IObitUnlocker.sys. I may just give up on Unlocker 'cause that driver is the heart of the utility. But now I'm venturing off-topic. (BTW IObitUnlocker is a file menu add-on; it finds which process has a file open and kills it so you can move.rename/remove the file.)
Again, Steve, thanks MUCH for your help.
