Serial number problem....

[Jonesy1760]

I need help with serial numbers....I keep getting "serial number is invalid"....how do I fix this problem?...I know they are valid since I have used them before in a previous installation....

I have one suggestion if you have got so many problems with installing and activating: verify the number with your Steam account and let it do everything for you.

I dont have a STEAM account!!!!

after downloading the steam setup when I click on it all I get is the Microsoft store page saying "the app your trying to install isn't a Microsoft-verified app"...what is this and how do I get rid of it?

Find your Windows setting, go to Application, there is one dropbox about how to obtain applications, check if yours is set to "only Microsoft Store", that thing prevents you from installing anything not in their store. Man I think you should really just ask Google instead of here.
