Before using Clibor, make sure to unzip the downloaded Clibor.zip.
If you double-click Clibor.exe directly inside Clibor.zip without extracting it, Clibor will not run and you may see an error like the following:
Clibor could not start because of an error.
ClbHook.dll was not found.
(This error occurs in version 2.3.4 and earlier. ClbHook.dll is not used in version 2.3.5 and later.)
Extract the ZIP file first, then run Clibor.exe.
