Unable to create Registry Key. Access denied.

Problem

When attempting to activate it using the code in your email (XXXX-XXXX-XXXX-XXXX-XXXX), it would not allow activation. What do I need to do? It looked like it should activate but would not accept the Activation Code. The error message after "connected" is as follows:

Unable to create Registry Key "\Software\AGG Software\Product Name" It is possible you don't have "read-write" privileges.

Solution

Please, launch the program as administrator (right-click over the program icon and select "Run as Administrator") and then activate the program.
