Re-Install, Activation and Registration of Sage 50 Premium 2017

SUGGESTED

We purchased Sage 50 Premium 2017 back on November 4th 2016. It was licensed to our company. I have the serial number, the account ID, the key code and the invoice from Sage giving us the download link, etc. We were allowed to have it on 2 computers so there was 2 users on the account.

I am trying to install it on my new computer. It is currently on my old computer and I have the window up that shows that it's licensed to our company. and the serial number and all that information is valid. However when I install it on the new computer and I try to activate and register the product it's telling me the information I am putting in is invalid. I have double checked the key code, the company name, the serial number and it is all entered correctly. Why can I not activate this on the new computer? Do I have to uninstall it from my old computer first??

Can anyone please help me?

Thank you!
