Question:
After we upgraded PPM to 15.4.1, we successfully upgraded Open Workbench on a client PC to a newer version that can be downloaded and installed from 15.4.1. However, when we try to open it from a PPM project, the following error message "The Default View file C:\VIEWSJAPATH\Gantt Chart.rwv does not exist" pops up.

The steps to reproduce the problem as shown below.

1. Upgraded Open Workbench by using an installer downloaded from PPM 15.4.1.
2. Launched Open Workbench from 'Open in Scheduler', the above error message comes up multipl times.

3. After we close the popup message, only Task name is displayed as an initial View, i.e. Gantt Chart is not displayed. Also, "Edit View" may stop and force to close Open Workbench sometime.
Answer:
The problem happens if existing Open Workbench and CA PPM Schedule Connect are not uninstalled. As documented on the following manual, we need to uninstall them before we install the new one.

From CA PPM - 15.4.1 > Install and Configure Open Workbench (OWB) > Uninstall Open Workbench and CA PPM Schedule Connect
--->
"Uninstall any existing version of Open Workbench and CA PPM Schedule Connect before installing a newer version."
