I have installed appian 21.4 on local (Win 10) . I have observed once I start the process model for debug or through action it's always stuck on start node itself.
I don't see any specific error in logs. but while starting the tomcat I'm getting below error:
Error on tomcat startup:

Seems like this path does not exist
java.nio.file.InvalidPathException: Cannot store the note content, because the location is not valid.: C:/appian21.4/appian/_admin/process_notes/exec/00/3/0
Yes that’s correct but should I create it manually? Because installation did not creat directory process_notes under _admin folder
What build version are you on? You can check in your Appian installation directory's conf/build.info. Apply the latest 21.4 hotfix. Hotfix 21.4.425.0 addressed an issue that is similar to what you're experiencing.
