If WebSphere Integration Developer (WID) V188.8.131.52 is installed simultaneously with V7, or is upgraded directly from V184.108.40.206 or prior V7.0.0.x release, then WebSphere Integration Developer V220.127.116.11 is unable to launch.
The screenshot below illustrates the configuration error observed when launching WebSphere Integration Developer V18.104.22.168 after going through the above described install/upgrade path.
The workaround is to upgrade to WebSphere Integration Developer V22.214.171.124 or V126.96.36.199 Interim Fix 001 first prior to installing or updating to WID V188.8.131.52.
For the upgrade problem, another workaround is in the file "<WID_Install>/Configuration/config.ini", specify the value "-Dorg.eclipse.update.reconcile=true" at the end of the file, then re-launch WebSphere Integration Developer V184.108.40.206.
