Install error reading from msi file -- cannot find

After I've downloaded the install file and clicked on it to fire up the install, it comes back with an "Error reading from file D:\Mimi\Downloads\MuseScore-2.0-beta2.msi. Verify that the file exists and that you can access it." Well, I couldn't have started up the install if I hadn't existed and been started!

I wonder if it has to do with the fact that my Downloads are on my data (D:) drive and not in the default C drive location. I suspect something hardcoded in the installation that's looking in the wrong place.

UPDATE: I WAS RIGHT ABOUT IT HAVING TO DO WITH MY DOWNLOADS BEING ON OTHER THAN THE C: DRIVE. I created a temporary Downloads directory under my user on the C drive and the install went through. PLEASE MODIFY THE INSTALL MSI TO REMOVE THE HARDCODED LOCATION INFORMATION TO PICK UP THE INSTALL FILE LOCATION NO MATTER WHERE IT IS.
