We have 50 users with Office 365 Business Premium subscription.
Office 2013 click to run installs perfectly on all PC's bar 1.
I login to office 365 and click on install now. This downloads the click to run installer.
When I click on run the screen flashes nothing happens
Windows 7 x64 with all updates applied. Domain attached PC and user has local admin rights
So far have tried
disabling firewall and all AV software
Ran SFC /scannow on PC as well as malwarebytes
ran disk cleanup
Logged in as domain admin but same issue
Any ideas would be gratefully received as very little further to go on
