Installing Hoster On Second PC
 

I am installing my first purchased copy of Hoster on a second PC. It goes through the process successfully. The version of Hoster is different and my e-mail address has changed. When I try to open Hoster after rebooting I get a messag Your serial number does not match your registration information. Please reinstall Hoster and try again. I have done this a number of times with the same result. What Can I Do!!!

you must have the same email address when you first bought your hoster program
do you have all the custom updates?, if not you must install all the windows updates (custom updates i mean )if you still have the problem
go to support and click on knowledge base..you should be able to find an answer to your question..if not i think you need to submit a ticket and tell them exactly what your problem is

You have to use the email adress that you have registered with for your store account. If you have purchased an upgrade that is different for the first number (ie version 2.xxx tp version 3.xxx) then the serial number will be different as well.
You also need to do a Remove and Re-install instead of Upgrade/Update.
