Exit Code 17006 when trying to update and Office 365 install with Project

Hi All,

I am getting the following error in the Office 365 install log files:

"C2R client returned failing error code 17006"

I have an existing base installation of Office 365 Build 1705, which l am trying to add Project and/or Visio to, using SCCM.

It has been working previously and l had the FORCEAPPSHUTDOWN=TRUE set in the office XML file, but was getting complaints from users that they were losing work as when the package ran from SCCM, it would force close all office apps

If l set FORCEAPPSHUTDOWN=FALSE, then l get the above error in the office install logs and Project and/or Visio do not install over the top of the base installation. Presumabley because outlook, word, etc is open. 

Any suggestions?
