I've installed version 4.0.89 from the official website and apparently it's working just fine on 64bit versions of Windows. I've installed it on Windows 10 64bit and it works normally.
You can download it from the following website: http://zpa.cz/sw/cdlwin4.htm
The file name should be: cdlwin4089.exe and the installation password is the version number. In this case it's: 4089.
