Well, after suffering through this error for many months, I finally decided to research the solution.
In my case, it was because the computer had Nero 7 Essentials installed. To solve the problem, I followed the following steps:
- Click Start | All Programs | Nero 7 Essentials | Tools | Nero Scout
- In the left hand column, click Indexing | Folders
- Click the Clear All button
- Uncheck the Enable Nero Scout item
- Click OK
And that was it.
