Error "You have chosen a disk with incompatible software: FAT32 file system"
Installation of a Kaspersky application can stop with an error if the disk you have chosen uses the FAT32 file system, which is incompatible. The application cannot be installed on such disk due to possible issues with access to program files.
To eliminate the problem, convert the disk file system to NTFS. For instructions, see the Microsoft support website. Then run the installer once again.
