Office 2010 keeps asking for key

Put in key and asks again in a couple weeks, Goes and reinstalls itself when I click on program that Recently used over and over again,

I'm confused.

What do you mean when you say MS Office reinstalls itself when you click on a recently used program.

What program?

What version of Microsoft Office are you using?

Is it Upgrade, Retail or OEM?

Where did you acquire it from?

Are you using the product key that was provided with the software?

Sorry about that it's an upgrade key for office 2010 64 bit 3 user pack that it keeps asking for every so often I put it in and works for a while. The it asks for and proceeds to say installings wor or excel,
I think this an issue because the upgrade was done from an oem ms office starter edition.

Have you activated the upgrade?

If you haven't you will keep being prompted.

Any other suggestions?

But it shouldn't be necessary.

Please confirm which version you are using and where you got it from.

Uninstalled preinstalled ms office starter and all other versions and real installed

That's great news.

Have the activation prompts stopped?
