sihost.exe error

Every day, mostly when playing Sudoku Classic, I get an error

"Faulting application name: sihost.exe, version: 10.0.22000.1, time stamp: 0x5c7a6c09

I have searched all over but cannot find a cure. Please help.

And since the latest update to version 22000.527, I also get Side by Side error

"Activation context generation failed for "C:\Windows\Installer\{95AC38B5-B548-4E7E-ABCD-AABCA2B39538}\recordingmanager.exe". Dependent Assembly rpshellextension.1.0,language="*",type="win32",version="1.0.0.0" could not be found. Please use sxstrace.exe for detailed diagnosis."

Also cannot find a solution.
