How can I associate Hypertrm.exe to .ht extension files in Windows 8

Question

I was able to add Windows XP Hyperterm to Windows 8 by creating a folder in Program Files (X86) and copying the appropriate Hyperterm entries to it (from another post).   It executes and works great.  When I save my session, it creates a .ht file
in the Hyperterm folder down in my User Files tree.  When I create a shortcut from this .ht file or click on it, Windows cannot associated it with Hyperterm.  When I try to associate it with Hyperterm it tells me Windows can do it.  
When I look for .ht files in the Associations, there is no entry for .ht.
How can I get around this so I don't have to start Hyperterm and do File/Open to access my particular sessions?
I've seen a lot of stuff about associations, etc. but nothing I've tried so far works.

Hi,
Have you tried this before?
Right click the .ht file, choose Open with.. and then in More options, scroll down and click Look for another app on your PC. Then locate your Hyperterm excusable file to see if it can work fine.
If it cannot work, this issue can be caused by lacking of mapping registry keys.
Please know how the file association work:
Files are exposed in the Shell as Shell items. To control file associations, application developers can register a mapping between the file type and the handlers (COM objects that provide functionality for the file type's Shell items).
When the Shell needs to query for the file associations of a file type, it creates an array of registry keys containing the associations for the file type, and checks these keys for the appropriate file associations to use.
Try following fix:
1. Double-click on your .ht file, and open it with Notepad
2. Enter your registry, and navigate to the following key: [HKEY_CLASSES_ROOT\ht_auto_file\shell\open\command]
3. Under the (Default) string, replace the Notepad.exe path with the path of your HyperTerminal application. It should look something like "C:\Program Files (x86)\HyperTerminal\hypertrm.exe"
4. Double-click your .ht file again. With any luck, it should open in HyperTerminal now.
