(adsbygoogle = window.adsbygoogle || []).push({}); I downloaded a tool and it said Diagnostic error, I clicked on the other file and that said "This program cannot run is DOS mode".

Anyone know how to fix this?

Locate the .PIF file for MS-DOS Prompt. You can use Windows Explorer, My Computer, or the Find command on the Start menu to locate the file.

The filename for MS-DOS Prompt is either MS-DOSPR.PIF or the long filename MS-DOS Prompt.PIF.

NOTE: You may have multiple MS-DOS Prompt .PIF files in different folders. For example, there may be one in the Start Menu folder and another in the Programs folder. Be sure to change the correct one.
Right-click the filename, and then click Properties.
Click the Program tab, and then click the Advanced button.
Click the MS-DOS Mode check box to clear it, and then click OK.
