OK. I have your answer. The problem is you are missing one file needed for it to install. Go to the following link and click on the download link at the bottom. Just run it and that should fix your problem.

After you have run this, restart your computer and then try to install Microstudio.
The problem is one file has been left out of the install package and this will be fixed in a new release soon. Sorry for the problem.
