Is your computer connected to the Internet?
If you were trying to register Microstudio I receive a failure notice, and I have not seen any for you.
You can read the installation instructions
by clicking this link and locating Microstudio and your 2.517 verson. Click the version number to go to the installation instructions page for that product.
Let us know the exact error message text, or what screen you see last so we can help you. We need more information to figure out how to help you.
