''The parameter is incorrect'' error is common with a bad CD burn or a corrupted partition table.

Look here

Or try to do a scandisk or chkdsk.

The ''parameter is incorrect'' is also usually an indicator that something is wrong with the Windows Installer shortcut for the application. Replacing the shortcut usually fix the problem.

Also, you need to check your file association. Your EXE files might be associated with command or dos prompt.
