What exactly is the SDXHelper executable, and how does it affect Microsoft Office?
I have recently started to evaluate the Office 365 suite by installing it on my Windows 8.1 machine. On at least 3 occasions now, while using OneNote, I have gotten an error message stating:
Microsoft Office SDX Helper has stopped working
While looking around at the foot prints left by the error, I was able to discover that the name of the module causing the fault is Mso30Win32Client.dll and that it seems to have been triggered by a memory access violation, but not much else. Performing a search with the terms SDXHelper seems to present a collection of articles about potential security issues and other standard template dribble. I was able to find some general trouble shooting documentation for Office applications that crash or cannot start on the Microsoft documentation web site which presents a workaround, but does not seem to explain anything past the point of what to do to work around the issue. This leaves me with the question as to why a fairly new installation is failing, and what is the process even doing. Since OneNote did not crash, I am lead to believe that it is not a critical process.
My first instinct is that this may be related to bad memory in my machine and I should probably run a memory scan one way or the other, but I am curious if this turns out to be some other issue, then to what extent is the SDXHelper a necessary process and how will it effect my Office experience if I am unable to keep it running?
Note: The Office suite was installed on a clean Windows 8.1 image downloaded from the Microsoft.com web site and no other versions of office programs have been installed previously.
