2.506 will Still not open

[sm58z]

After trying the advice of:

Uninstalling MicroStudio, downloading all available Windows Updates, reinstalling Microstudio and Re-Starting the computer the same problem Remains:

After a successful install, when I click on the icon, the hourglass appears like the program is going to open but it never opens and the hourglass just goes away. If I hit control, alt, del, Microstudio shows in the dialog box as being open, yet the program never appears on the main screen.

What should I try next?

Thanks, Brian
