Hi,

It looks like you're encountering two main errors during the installation of Microsoft System Center Virtual Machine Manager Server (x64): Error 1168 and Error 1720.

Error 1168

This error typically indicates that the installer is unable to access certain files or resources. Right-click the installer and select "Run as administrator".

Error 1720

This error suggests that a script required for the installation could not be run.

Here are some steps to troubleshoot this:

1. Ensure that Windows Script Host is enabled on your system.
2. Open Command Prompt as an administrator and run the following commands:

msiexec /unregister
msiexec /regserver
