How To Fix McAfee Antivirus Error 12152

Manually editing the Windows registry to remove invalid Error 12152 keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely!

 

To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to Error 12152 (eg. McAfee Antivirus):

  1. Click the Start button.
  2. Type “command” in the search box… DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type “regedit” and hit ENTER.
  8. In the Registry Editor, select the Error 12152-related key (eg. McAfee Antivirus) you want to back up.
  9. From the File menu, choose Export.
  10. In the Save In list, select the folder where you want to save the McAfee Antivirus backup key.
  11. In the File Name box, type a name for your backup file, such as “McAfee Antivirus Backup”.
  12. In the Export Range box, be sure that “Selected branch” is selected.
  13. Click Save.
  14. The file is then saved with a .reg file extension.
  15. You now have a backup of your McAfee Antivirus-related registry entry.

The next steps in manually editing your registry will not be discussed in this article due to the high risk of damaging your system.

 

Clean Out Your System Junk (Temporary Files and Folders) With Disk Cleanup (cleanmgr)

 

Over time, your computer accumulates junk files from normal web surfing and computer use. If this junk isn’t occasionally cleaned out, it can cause McAfee Antivirus to respond slowly or provides an 12152 error, possibly due to file conflicts or an overloaded hard drive. Cleaning up these temporary files with Disk Cleanup might not only solve your 12152 error, but can also dramatically speed up the performance of your PC.

How to run Disk Cleanup (cleanmgr) (Windows XP, Vista, 7, 8, and 10):

  1. Click the Start button.
  2. Type “command” in the search box… DO NOT hit ENTER yet!
  3. While holding CTRL-Shift on your keyboard, hit ENTER.
  4. You will be prompted with a permission dialog box.
  5. Click Yes.
  6. A black box will open with a blinking cursor.
  7. Type “cleanmgr” and hit ENTER.
  8. Disk Cleanup will begin calculating how much occupied disk space you can reclaim.
  9. The Disk Cleanup dialog box will appear with series of checkboxes you can select. In most cases, the “Temporary Files” category will occupy the most disk space.
  10. Check the boxes of the categories you want to clean and click OK.
