Issues Opening HLB Files

OpenVMS Isn't There

When trying to open your HLB file, you get the error "Can't Open HLB File Type". Generally, this is experienced in %%os%% because OpenVMS isn't installed on your PC. Your operating system cannot associate your HLB with OpenVMS, so double-clicking the file won't work.


Tip: Another HLB-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Outdated OpenVMS

Your VMS / VAX Help Library file is incompatible with OpenVMS because you might have the wrong version installed. You will need to download a newer version of OpenVMS if you don't have the right version. Most of the time your VMS / VAX Help Library file was created by a newer OpenVMS than what you have installed.


Tip: You can sometimes get hints about the right program version by right-clicking on the HLB file, selecting "Properties", and looking at the version information.


Primarily, problems experienced when opening HLB files are due to having the incorrect version of OpenVMS installed on your computer.


Associated Difficulties Loading HLB Files

Even with the correct version of OpenVMS installed, you can still experience difficulties opening HLBs. If you are continuing to have errors with loading HLB files, other external issues might be to blame. Additional factors include:

  • Windows Registry HLB file paths that are incorrect
  • Corruption of the HLB file description inside the Registry
  • Corrupt install of OpenVMS or other HLB-related program
  • Your HLB can't be loaded properly (file corruption)
  • Your HLB has adversely impacted by malware
  • HLB-related hardware has device drivers that obsolete
  • Windows has inadequate resources to open your VMS / VAX Help Library file
