Hello
It could be related to the user running the spectrum process.
I had a similar error message when i tryed to use a diffrent user then "SpectrumRoot" to start the spectrum process.
I had to use the following:
install folder\ca\spectrum\lib\SDPM>processd install username servername\spectrumroot --password [spectrumrootpassword]
This will then give the following output:
Requesting installation of service: "SPECTRUM Process Daemon"
service already installed: requesting reconfiguration
reconfiguration successful
I dont know if there could be some diffrence in user/password from 9.0 to 9.1 but it cant hurt to try.
<EDIT>
Forgot to mention, that the SpectrumRoot user has to be a local admin, or this can also give allkinds of problems.
We have a secuity policy that removes local admin, from all local users, when it finds them.
So i have to add the user to local admin, before starting Spectrum.
