I'm installing Command Suite 18.104.22.168 (Device Manager only) on Windows Server 2008 R2 SP1 Standard, VMWare virtualized. Installation aborts with
KAIB64123-E (An attemp to read a return code failed)
Progress = 45
Execute <snipped path>\HCS\setup.exe /s /v "/qn UNI_SILENT_PARAM_FILE=C:\_hinst2_\param.xml" > ....
command exit code 
Not found: c:\_hinst2_\result.xml
any thoughts before I open a case ?
