ModDB tends to have slower downloads on larger files and nobody could be bothered to split it into archives most likely.

For those who would like to know, you can use InnoExtract to verify the 6 files using the 'test' option.

Just pass the small EXE file to InnoExtract and it will do the rest of the files (BIN) too. Similar to how it works with GOG installers, except the BIN files have been limited to 1.9 Gb each in this instance.

NOTE - This was after extracting them from the ZIP files.
