Notes:
This issue will only occurs for backup client who auto upgraded from version 5.2 to 5.5.

Cause

The ObmJW.exe file (for AhsayOBM version 5.2) has been renamed to javaw.exe (for AhsayOBM version 5.5).

Resolution

1. Open a command prompt
2. Navigate to the following directory:
   
   (For MS Exchange 2003) ${OBM-Install-Home}\jvm\bin
   (For MS Exchange 2007) ${OBM-Install-Home}\jvm32\bin
3. Enter the following command according to the error message shown:
   
   Example:
   copy javaw.exe ObmJW.exe

   or

   copy javaw.exe bJW.exe

   This will copy the javaw.exe file into ObmJW.exe or bJW.exe within the same directory

   Notes:
   ${OBM-Install-Home} is the AhsayOBM installation directory, which by default is C:\Program Files\AhsayOBM

4. Restart the AhsayOBM scheduler service
