Acronis 12.5 doesn't recognize installed hyper-v role
I try to re-install Acronis 12.5 virtual host latest build on a Server 2016 Standard (not core) with working hyper-v role. I had some trouble with the former 12.5 installation, so I uninstalled it and now try to get it back on the machine.
During the setup routine, I go to advanced options and have to check the desired installation options.
The "Agent for Hyper-V" is missing, at the bottom of the list I get an explanation, that the Agent for Hyper-V can only be installed on Servers with Hyper-V Role.
In fact, the hyper-v role is installed and works fine : )
Why is the setup not recognizing my installation? I checked all hyper-v services, all are running.
Any help is highly appreciated!

Dear Vasily,
thank you very much for your quick and detailed information, in the end the solution was different, but your answer guided me towards the right direction:
Short version: Windows Modules Installer Service was set to disabled
Long version: Checked if Hyper-V Management Tools were installed: OK
Checked if WMI worked: Query always failed "unrecognized command"
Checked with other power shell queries if hyper-v roles are recognized to be installed: OK
My conclusion: Maybe the hyper-v mangement tools are corrupted, so I decided to remove these features and reinstall.
While trying to remove the features via server manager, got error message "0x80070422 Service not found or disabled"
Checked all disabled services -> found Windows Modules Installer. Re-enabled and started service, started Acronis installer again and voilá.
Thanks again for your great support!
