Try these suggestions in order:
1.) Try to run the installation with everyone out of Essential Forms.
2.) Try the Update from another computer or a computer with admin permissions.
3.) Try to install directly on the server.
4.) You might need to contact your network administrator to install the Update due to permissions.

5.) a. Open Essential Forms and click View>System Info. Under "Directories" make a note of the Program and Data paths (in blue). Close the program.
b. Compare the registered Program path and Data paths from a. above (View>System Information) with the program and data paths in the error message.
Based on what was found in 5a&b above, try one of the following (I, II or III):
I. If the registered program path or data path is NOT the correct location in the error message, try the following:
If when installing on the local workstation you get an error message, "The Registered Directory Either Doesn't Exist Or Isn't Available At The Moment" you might need to modify the stored paths for the Essential Forms "data" folder stored in the registry by going under Start, typing REGEDIT in the search bar. The paths that would need to be deleted:
HKEY_CURRENT_USER>Software>Essential Publishers>Essential Forms>ProgramPath And DataPath: right click and modify keys "MainProgramPath" And "MainDataPath"
Try to run the efinstaller.exe again.
II. If the registered program path in the error message doesn’t match the Essential Forms shortcut>Properties>Target on the Desktop, try the following:
If the Essential Forms shortcut>Properties>Target on the Desktop doesn't match the registered program directory, you may want to launch once with the ' /r' command-line switch on the shortcut (or else draw a new shortcut from the registered program directory.) Right-click on the Essential Forms shortcut click Properties in the drop-down, click the Shortcut tab, in the Target window put the cursor at the far right-end (outside of the last closed quote if there is one) then press a space <spacebar> and type /R
Ex: "C:\Program Files (x86)\CEB\Essential Forms\EFWin32.exe" /R
Click “Apply” and “OK”. Run the program once in that mode and go back and remove that /R off the shortcut.
See if you can now run the efinstaller.exe without the error message.
Since the shared registered data directory was already updated from another workstation, we shouldn’t need to run JC Update again on this station. The data folder is only receiving our update files right now, not new program versions.
