yammer and teams msi installations fail when used during OSD deployment
using both 64bit msi installations of yammer and teams on windows 10 1803 64bit. Upon login of a new user windows trys to kick off both installations and one of them (usually yammer) gets clobbered. the end result is teams does get installed (the prevent auto-launch install switch is not working) and yammer fails with a error message an log. the log suggests it couldn't access the squirrel directory to retrieve the update package. if you close the error>log off>log back on> the yammer installation completes.
