Issue installing Secure Browser

I recently purchased a new computer but am having trouble downloading Secure Browser.

Every time I try to download it the following message pops up:

Program Compatibility Assistant
This app can’t run on this device
Avast
Avast Software*
This app can’t run because it causes security or performance
issues on Windows. A new version may be available. Check
with your software provider for an updated version that runs
on this version of Windows.

An error occurred installing Avast Secure Browser.
Please visit the Avast Secure Browser website for help.

Does anyone have any ideas on fixing this?

You really are going to give more information.

e.g. the questions I asked in the topic in the General forum.
