Here are step by step instructions for installing LHA, an optional external program required to work with LZH files.

1. LHA is distributed as a self-extracting archive called LHA213.EXE. First download LHA213.EXE.
   
2. Use the File Manager or Explorer to create the folder C:\LHA. You can use a different folder but then you will need to substitute that folder name in the following instructions.
   
3. Use the File Manager or Explorer to copy LHA213.EXE from your download folder to the C:\LHA folder.
   
4. Double click on LHA213.EXE to run it. This will cause the files in LHA213.EXE to "self-extract" into the C:\LHA folder. Then go back and delete C:\LHA\LHA213.EXE, as it is not needed for day-to-day work with LHA and WinZip.
   
5. Start WinZip. Pull down the Options menu and select Program Locations.
   
6. In the LHA field in the Program Locations dialog box type

c:\lha\lha.exe

and press the OK button.

That's all there is to installing LHA. You can now access .LZH files (created by LHA), or create them, the same way you access/create Zip files.
