Microsoft Visio 2010 is an excellent tool to draw various objects, including network schematics.
However, my Visio 2010 under Microsoft Windows 7 Ultimate (64 bit) kept crashing
Same here, remove the add on.
In Visio select File/Options/Add-Ins/
Manage COM Add-Ins/Click Go
Select ‘Send to Bluetooth’
Click Remove
Yeah finally this worked for me Tools -> Trust Center -> Add-ins-> Check “Disable all aplication Add-ins”.
There a long-standing issue with Bluetooth add-ins. Most other add-ins should be fine.
