If the installer fails, here are some possible solutions.
If it doesn’t detect the Serena Common Web server, the installer may fail with a message similar to this message:
"Common Tools files are missing from the install. Please ensure these files are present under the common folder before continuing with this install."
If you have Serena Common Web services installed, check to make sure the services are started. If they aren’t, start them.
If you do not have Serena Common Web services installed, you must make sure the Common folder for the Serena Common Web services installer is in the same directory as the Release Control.exe file and that the folder has the Common Web services files.
