When you start Windows XP, you receive:
RUNDLL
Error loading irprops.cpl.
The specified module could not be found.
This error will occur if the Bluetooth Authentication agent is installed and you are missing a required .DLL file, or if the Bluetooth Authentication agent was uninstalled and its' registry Run Value Name still exists.
To resolve this problem:
1. Open Control Panel.
2. Open the Add or Remove Programs applet.
3. Scroll to Bluetooth Authentication agent and press Change/Remove.
4. When the Bluetooth Authentication agent has been removed, close Control Panel.
5. Copy / Paste the following to a BTA.reg file:
Windows Registry Editor Version 5.00
\[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\]
"BluetoothAuthenticationAgent"=-
6. Merge the BTA.reg file with your registry, or run regedit /s BTA.reg.
7. Shutdown and restart your computer.
NOTE: If desired, you may now install the Bluetooth Authentication agent.
