How can a piece of Software called "Rational" be anything but.
A console for the license server that doesn't output error messages at all when run as a service. When run from a command shell it doesn't display any error messages but informs you that they can be turned on if you desire - this is when in the background there are fatal errors happening preventing the thing from starting. It's great! Oh, and don't think I'm overlooking messages in the event log, or somewhere like a custom named log file - I'm not.
The Client install takes forever to decompress, while displaying their corporate motto that is utterly meaningless and yet probably cost 20 consultants 10000 billable man hours between them in "brainstorming" sessions to devise.
At the moment, the server is running - not 100% successfully, but it's running. IBM, you bought this piece of crap for a reason, how about making it more logical now?
On a side note - if you send someone a cd containing 2 versions, say, version 5 and version 6 of a piece of software - what would you expect them to do? Install version 6, and then version 5 over the top, and then wonder why it's not working? Indeed I didn't expect that either..
