Currently you can make face-to-face video chat with friends though the Facebook webpage. The function worked fine in Win 8, but it just stop working after upgraded to Windows 8.1 Pro. I can’t find the video calling button at the top or on any friend’s profile, and also get the “msvcr110.dll was not found” error message.
For many people, the Facebook video calling/chat button just has been disappeared with Windows 8.1 updates. I use compatibility mode and do a clean boot but nothing happens, then open event logger and notice the information below:
“FacebookVideoCalling.exe, version: 22.214.171.1247, time stamp: 0×50775885
Faulting process id: 0x1f68
Faulting application start time: 0x01cecb51b2458965″
Here are tips about how to resolve the problem:
* Change the User Agent for IE browser
1. Open IE11 to access Facebook , and login using your account.
2. Press F12 from your keyboard to enable developer tools mode.
3. In the left hand, scroll down to locate Emulation mode, and setup the User Agent string as IE 10.
* Another workaround is to use Chrome or Mozilla.
1. Simply right-click on the google chrome launch icon.
2. Select Properties from the pop-up menu.
3. Go to the compatibility tab, choose “Windows 8″ from the list, and click Apply > OK.
* If these are still not working, you have to wait for microsoft’s patch.
