I had a client call in the other day, telling me that her computer would freeze up and display error messages whenever she opened Windows Explorer. The error message said
Cannot load BTrez.dll- NW. Checking BTrez.dll with ProcessLibrary, I found that the error referred to a problem with the drivers for Bluetooth.
To resolve the problem, I did the following:
- I opened Computer management, then turned to Device management
- I found Bluetooth devices, then right-clicked and selected Uninstall
- Once the uninstall was complete, I scanned for hardware changes
After the scan, the bluetooth module reinstalled, and worked correctly.
