This is a command-line tool, as it has no UI. You can open the Windows Command Prompt and use the  command to change to the directory where the LHDecompressor executable is. Then, get the LH-compressed file you want to decompress, and put it in the folder with the executable. Now, type the command (the top command is for v2.0 and the bottom command is for v1.0 only):   where   is the version of the executable you downloaded, x86 (for a 32-bit Windows OS) or x64 (for a 64-bit Windows OS). is the name of the LH-compressed file and  is the name you want the decompressed file to be. The name of the decompressed file should not end with the  file extension. For example:
