I recently had an email asking me what was wrong with their Workflow Builder installation – whatever they did no icons were appearing in the Builder.
Also, there was no Standard item type being opened – when the user tried to create a new Item Type using the quickstart wizard, they got an error message – and it wasn’t even a nice one, as it looked like the messages file hadn’t been installed correctly and all they got was an error name and code.
Some years back, I had exactly the same problem when I had installed Builder on a machine on client site. The installation process had “worked” correctly (i.e. Oracle hadn’t reported any errors), but obviously there was something wrong.
The problem was that the user I was logged in as did not have FULL admin rights on the machine – it had enough to make most of the install work and write some information into the Windows registry, but not enough to actually install EVERYTHING required.
So, the quick fix is to make sure that you are logging into the machine as someone with full rights (typically log into the machine itself rather than onto a network) and then do the install.
