System Center Virtual Machine Manager 2025 fails to install

Hi,

  We're migrating to HyperV because of the excessive cost of Vmware and to complete our project we need to install Virtual Machine Manager, unfortunately we haven't had any luck as it fails because of the below issue.

Error 1720. There is a problem with this Windows Installer package.

A script required for this install to complete could not be run.

Custom action ConfigWsman script error -2147221503, Line 312, Column 9

I have tried with Windows Sever 2022 and 2025 and follow all instructions but have had no success.

Even tried Virtual Machine Manager 2016 and same issue occurs.

Has anyone had any success as this is a major blocker for us?

I can provide logs.

Any help would be greatly appreciated,.
