How to install True Image 2017 on Windows 11 without Try&Decide?

Thread needs solution

I have an 'eternal' license for Acronis True Image 2017. As Try & Decide was incompatible with Windows 11 memory protection, I was advised to uninstall Acronis That fixed Windows 11.

Now I would like to reinstall Acronis without Try & Decide. But this seems not possible, as the installer does this by default (build 8065). I am asked to switch off Windows 11 memory protection....

I read that from build #40107 Try & Decide is not installed by default, but how do I upgrade to that version? I don't mind paying a bit for my upgrade, but I don't want to pay an annual fee. What version would be installable without Try & Decide (which I don't need anyway...)

PS I also have a eternal license for 2014.... Would that work on Windows11.

The Try & Decide incompatibility with core and memory isolation under Windows 10 and 11 is very annoying. There is no way of doing a selective installation with ATI 2021 or earlier. What you need to do is disable core and memory isolation, install ATI 2017, There are several possible ways to then disable Try & Decide:

  • registry hack (see here)
  • Follow this advice from Steve Smith

Folks, there is a fairly simple way of resolving this issue provided that Acronis Try 'N Decide is not being used, which is to rename the C:\Windows\System32\drivers\tib.sys file then do a Windows restart, i.e. I renamed the file to tib.~sys and was able to turn on Core Isolation.

Note: I also had to follow the steps shown in webpage:  - because the scan showed that there was another incompatible driver installed with Windows 10 that needed to be removed.

Once the above actions were done, Core Isolation was activated by a further restart.

Hopefully Acronis will eventually realize that this issue is causing significant reputational damage and take appropriate action. I can think of several easy ways to overcome the problem ...

PS: as always, before editing the registry make a backup in case things go pear-shaped.
