This week I installed IBM Connections 5.5CR1 on a Windows Server. I used WebSphere Application Server 18.104.22.168 and everything ran pretty smooth, but the Connections install itself ended in an error after all applications were successfully installed.
The popup showed a regexp error and a long string. The installer ran through the night, so I couldn’t remember this string and started the install again. The Same message box appears after everything was successfully installed (checked through ISC, after the error everything was uninstalled by the Installation Manager) and even the install.log showed nothing special.
This time, I remembered the string, it was the password of my WebSphere Administration user! The password looked like this:
After removing the bracket and replaced it with another special character everything was installed without error. So be careful with special characters and IBM Installations.
I never had an issue with special characters, but I know that the Sametime documentation mentions that space, @ and ! can be a problem.
