Thank you for contacting AVG Community support.

Since you are unable to download the application due to user access restriction on your computer, please contact Microsoft support to resolve the issue.

Thank you for your understanding.

From your description/message, it seems that the inbuilt admin privileges needs to be enabled. It would be appropriate if you reach MS support or your system's manufacturer to fix this.
Thank you for your understanding in advance!
