Syntronik GS-V installation error

[KenV9999]

I have redownloaded GS-V multiple times and every time I get a JS error and an indication that part 4 is incomplete (SYN2_GS-V_Part_4.zip). Indeed WinRAR also gives me an error.
I have tried deleting it and re-downloading it multiple times and I get the same error every time.

It is showing a size of 558,784 KB and WinRAR throws an "Unexpected end of archive" error.

Anyone else with this issue or a solution?

Just for info, the Part 4 ZIP file is 4.16 GB here.

Thank you @DarkStar!

Based on the files I downloaded today, it looks like they corrected the part 3 and part 4 files so the installer and Sound Content is no longer embedded within another folder. So maybe the file error was a result of the corrected file being uploaded. Just a guess.
