Getting this error:
xplorer2_CommPort: xplorer2_64.exe - Entry Point Not Found
The procedure entry point _Atomic_fectch_sub_4 could not be located in the dynamic link library MSVCP110.dll

Any suggestions?

this isn't coming from xplorer2, probably it's one of your shell extensions
if you installed something recently (e.g that adds items to the shell context menu) then that's your prime suspect

A little googling suggests that the primary source of this error is installing anything related to Office 2013, especially in conjunction with Visual Studio 2012 (though not exclusively). As Office 2013 no doubt installs more shell-extension oriented fluff than even my teddy can imagine, that might be a place to start. (Plus the usual suggestion of updating the relevant C++ Redistributable Packages, though that's a little too obvious, and if there's one thing that MS is good at, it's generating error messages that have no relation to the actual cause.)

Seems to have been an Adobe update that morning. A search of MSVCP110.dll found a new version of that file in an Adobe path.
