OxeOO1O406 (AVG Error Code)

I cannot uninstall two products.  I installed another AVG product and it asked for a License Number (had no idea it required one).  Here is the message I always get:

"AVG is not able to recognize your License Number.

Please click on Re-enter and enter your license number again.
If does not resolve the problem please reinstall AVG."

The problem, I cannot uninstall both products at all.  States I first have to uninstall the product requesting a License Number.  I never had one!  I would like to uninstall the one App. then  install the AVG free App. again.
