Hello, please clarify the following:
1. What is your Operating System?
2. Recently did you make any changes to your computer like System Restore?
3. What happens when you try to execute DMSetup.exe, are you getting any error message if so please upload the screenshot of the same
Operating System: Windows XP
No changes were made, I did not do a system restore
When I execute 'DMSetup.exe', i get an "Open File - Security warning" Box, with a "run" and "cancel" option.
On clicking "Run" option, warnig box disappears and no installation takes place.
Alright, since you have specified as you are able to find the McAfee folders then it's always recommended to remove them off by using the removal tool and then try installing them back. You can click on the Useful Links on top of this page to run the McAfee removal tool (MCPR)
In addition to that, you may also check for Windows Update and make sure you install all the available windows updates to your computer. Hope this would help you...
