Hi silvo77,
Adding to BossDweebe's suggestions
Some commands/programs might require elevated or administrative privileges. To run these commands, you can use the Run as administrator command.
To install the program in administrator mode, follow these steps:
a. Locate the program icon, right-click click “Run as administrator”.
b. When the UAC message is displayed game in administrator, do one of the following:
i. If you are logged on as a standard user, or if UAC is configured to always require credentials, enter the appropriate administrative credentials, and then click OK.
ii. If you are logged on as an administrator and UAC is not configured to always require credentials, click Yes to start the application.
Proceed with the installation and check if that solves the issue.

Hope this information helps.
