I have a problem with Microsoft Excel;
Each time I open a file in MS Excel. Excel pops a message saying "MS Office Excel has encountered a problem and need to close" and it gives me an option to "Recover my work and restart MS Office Excel".
Click on Start > Run, type regedit and click OK.
After that navigate to: *HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\BtOfficeAddin\BtOfficeIntegration
