The DVD contains two self-extracting, compressed archive files, one for the WLD and one for the MTC data. Insert the disk into your DVD drive, then view the files with Windows Explorer. Double-click on each file and follow the prompts to uncompress the data. If you accept the defaults it will put the WLD data in c:\kr_ital_wld and the MTC data in c:\kr_ital_mtc, but you can change these to install in another place. Finish the installation by configuring with CheckerBoard the Database Directory, Endgame DB cache memory, and mtcpath as described on the KingsRow Italian homepage.
