This error means that the shortcut is unable to locate the Java executable, this means that Java JRE has been uninstalled or updated.
When JRE is updated more often then not the java binaries are moved to a new folder for that version, which means the static DS-Client shortcut can no longer access these.
To resolve the start menu shortcut, do the following:
1. Browse to C:\Program Files\Java\ and note the latest version folder ie.jre1.8.0_51
2. Open the properties of the DS-User Shorcut For most modern operating systems this is:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Asigra DS-Client\Classic DS-User
3. Modify the Target Path with the lastest Java version folder, ie. if the latest Java version folder as discovered in Step 1 is jre1.8.0_51 :
Change the existing path from
C:\Program Files\Java\jrexx.xx.xx\bin\javaw.exe" -jar "C:\Program Files\CloudBackup\DS-Client\dsuser.jar"
C:\Program Files\Java\jre1.8.0_51\bin\javaw.exe" -jar "C:\Program Files\CloudBackup\DS-Client\dsuser.jar"
4. complete steps 1-3 for any aditional custom shortcuts created
