Spectrum Online backup fails

Issue/Introduction

Since the last Windows update, Spectrum OLB fails and onlinebackup events show the temp directory failed to be deleted. 

Cause

The OLB process successfully creates the .SSDB backup but does not delete the temp directory and does not compress the SSdb to .gz for synch to secondary.

We tested the rm command from a bash shell and got an error on msvcr120.dll  We searched for this on C:\Windows but it did not exist.

Resolution

Copy msvcr120.dll from a working SpectroSERVER on a similar Windows OS.  It exists in C:\Windows\SysWOW64 and C:\Windows\System32.

After this the backup worked.
