Von, George is correct. The upgrade is FREE only if you have kept your download email. If you have lost it you will have to order the Microstudio25UpG part number for $15.
Depending on when you ordered, your download email will be titled either:
MTU product download instructions - The current name, or
MTU.com product download instructions - we had to remove the ".com" to prevent AOL from saying we are spam.
Enter the text above into your Email program "search" capability (may be Edit menu, Find... commnand).
Once you find the download email, read and follow the instructions in it.... AND... save it in a safe place. The link within it will deliver the new mstudio2604setup.exe file to install Microstudio 2.604.
