Hello,
I'm using 14.0.2 and I am having some problems with multiple instance installs.
I am installing from the command line:
<exe name v1>.exe /NewInst "InstanceName" -- installs as expected
<exe name v2>.exe /UpgrdInst "Instance guid" -- get prompted to modify, repair, or remove
Installing through the exe installation wizard, the install works as expected.
I need some assistance to get the Upgrade to work on the command line.
