Finally found a FIX for 1534 error !
1. Open Regedit and navigate to the following two keys
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileNotification
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\ProfileNotification
2. Under ProfileNotification check if you have the TDL key
3. Export the TDL key at each location
4. Delete the TDL key at each location
5. Reboot PC to verify
Note:
You'll need take ownership of the TDL Key to be able to delete it.
Right-click on the key, select Permissions.
In the permissions for.. dialog, click the Advanced button, then click the "Change" link in the Advanced Security Settings dialog.
Enter your domain\username in the edit box, click Check names and ensure it finds your name
Click OK
You should be able to delete the key at that point. If it doesn't want to, try deleting each item in the key, then the key itself.
