Hi Lieven:
Glad you got it working, but to repeat what Mike mentioned, redhat 7.4 is not supported for 3.2, and that may be the cause of the error you got. There may be some difference in that version of redhat that caused the issue you saw
That said, you could check for a file called /var/.com.zerog.registry.xml. That is the file installanywhere reads to see if it is an upgrade or a fresh install. The install tries to read that from that file (inside InstallAnywhere). If it does, it uses that. if not, I'd assume that it sets it based on their choice for where to install to.
Given that you are all set, I am going to close this thread
