Can download installation file (msi) but cannot run it.

I can download the msi file but I cannot run it. Error message: Windows cannot access specific device, file, or path. You may not have appropriate permissions to access them. I did receive: Your license was issued.
Your activation key is: 3d6febd1-78ef-4d27-921d-996b5b64093a

this error can happen for several reasons but I would check your permissions in the first place. Then let me know if it helps. Thank you.
