Note: During custom installation, Lingvo will rebuild the index and may require additional disk space to store temporary files. These temporary files will be stored in the folder into which ABBYY Lingvo 10 is being installed and in the Temp folder of your operating system.
If there is not enough space on your hard disk, the setup program will display a message asking you to free up disk space and telling you how much space should be freed. You can obtain this information beforehand by clicking on the Space button in the Custom Setup dialog. In most cases, you will need 150 MB (including 35 MB in the Temp folder) for the Multilingual Dictionary and 70 MB (including 20 MB in the Temp folder) for the English-Russian Dictionary.
