install, cobsetenv and Group not found

I've tried a few times to google the following: "microfocus setup linux cobsetenv parameter". One of the links returned is:

Download and Installation Procedure - Micro Focus Community

Before installing on Oracle Linux, you must create a number of symbolic links. ... To install in a different location use the -installlocation="Location" parameter to specify an alternative directory ... /opt/microfocus/VisualCOBOL/bin/cobsetenv ...

which looks as though it's going to help. Whenever I click on the link though I get:

Group Not Found
The requested Group cannot be found.
Could you please help me to get to this link. Alternatively you could send me the docu about the symbolic links I need
