Lync 2013 Desktop does not start on WIndows 8.1

Question

My Office 365 version of Lync 2013 64bit crashes every time I start it.  There is no error message just the "Microsoft Lync has stopped working" message with Close option.  In further looking for a solution, I found the suggestion to
uninstall the Intel Bluetooth drivers but my system uses Realtek Filter drivers.  I have looked  in the event logs and found:

A lot of sites suggest to uninstall Intel Bluetooth drive but I does not have Intel Bluetooth.

Answer 1

Go to your computer manufacturer’s website and update all driver packages for your computer, especially:
Audio drivers
Bluetooth drivers
System chipset drivers
webcam drivers
Important Note:
If you use office 64 bit, Lync 2013 must be 64 bit also. {And vice versa, If you use office 32 bit, Lync 2013 must be 32 bit}
