What should I do if I see “Runtime error 339 Component DHTMLED.OCX is either missing or invalid” when installing PG Offline?
A.     DHTMLED.OCX is an Internet Explorer file used by PG Offline. Occasionally it does not register correctly, or the currently installed version does not work with PG Offline. Check for the presence of the file dhtmled.ocx in the directory C:\Windows\System32. If the file is present, run command (Start -> Run) regsvr32.exe C:\Windows\System32\dhtmled.ocx. If this does not help, it will be necessary to reinstall Internet Explorer. If neither of those two solutions work, you have an error in your system. I have had a user report that they fixed this by running Ontrack Fix It utilies available here Q.
