We have created an updated version of Javelin 64 bit which creates the Javelin Extensions directory path in the same drive as Javelin is installed. If possible I would request you to do a fresh install of this version and do your tests.
Please download the same from the link below and let me know how things work.
Javelin-4.8.121.0.zip (Please contact Broadcom Support to get this version or later)
If Javelin is getting installed in E: drive the Javelin extensions directory would be
E:\ProgramData\CA\JavelinConfig\Extensions
In case Javelin is installed in D: drive, the Javelin extensions directory would be
D:\ProgramData\CA\JavelinConfig\Extensions
Please note that we are creating the directory purely based on the drive where Javelin is installed and NOT on any environment variable like CATDMWEB_APPDATA.
Here is the step by step process:
1) After installing Javelin in C Drive, launched Javelin Designer UI and close it
2) You wanted ProgramData to be used from E drive
3) Copied the JavelinConfig from C:\ProgramData\CA to E:\ProgramData\CA
4) Opened the Javelin.exe.config located under C:\Program Files\Grid-Tools\Javelin folder updated JavelinProgramDataDirectory under appSettings section update the drive letter to the respective drive E in this case.
5) Similarly in the file JavelinExecutor.exe.config, added the entry from Javelin.exe.config related to JavelinProgramDataDirectory in the appSettings section.
