1). Just download the distribute archive [BASE is mandatory for Productive version], and expand (unzip) it into desired (non-root!) directory.

2). Download additional plugin pack(s), if needed. Put desired plugins into Plugins folder. Free trial version doesn't use plugins.

3). Run CheckLog.exe and create CheckLog.mdb file automatically during the first run (folder DB must be empty before the run).

Don't forget ask for activation key, you need it for productive version. All plugins connected to the kernel do not require activation.

Enjoy!
