Administrator control please?

Good morning everybody. Looking for some help please.

I have recently Installed a new Replacement Hard Drive with a new Windows 10 Installation.

However, now when trying re-Install my games which iv'e played In the past without any problems

I Am being told "An Administrator has blocked you from runnung this app Contact the Administrator"

I thought I had always been the Administrator!!!

Can you please advise me the best way to get back full Administrator Control of my Computer.

Many thanks

    Sometimes, antivirus or security software blocks app execution. Temporarily disable them to test if that's causing the issue.

    It sounds like windows is blocking the installer due to User Account Control (UAC) or SmartScreen, even though you're the only user. This can happen a fresh install when your account isn't fully recognized as the built-in administrator or when security settings are strict. 

  • It looks like you lost the admin rights somehow.

    If you're getting UAC prompt with neither No nor Yes button, this shows lack of access rights. 

    Some third-party programs or company/work account may also create such restriction.

    Please refer suggestions in this fix and let us know if this helps:
