Problem with frequent Excel crashes

 2009-02-26    Problem solving    3    142

After buying the Office 2007 version I started to experience a lot of crashes in Excel 2007, especially when closing workbooks and opening new workbooks. After each crash I found something like this in the Application Event Log on my laptop:

Faulting application EXCEL.EXE, version 12.0.6331.5000, time stamp 0x48fa2869,
faulting module OLEAUT32.dll, version 6.0.6001.18000.......
Send to Bluetooth (btsendto_office.dll). Since the Excel application did not allow me to uninstall it from the user interface, I had to do it in the Registry Editor:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\BtOfficeAddin.BtOfficeIntegration.1
Find the key LoadBehavior and change it from it's current setting (normally 3) to 0 to disable the addin. When you start Excel again, the troublesome Blutooth addin should be gone, and the frequent crashes too.
