Unomysteez

Hi all, Any help would be appreciated. Even just a hint in the right direction. I have the Eggman Teknoparrot files 1.5tb). I go to extract/unzip with 7z. Only approx 20% of the files will extract and give me an .exe file so I can link up with Teknoparrot. Am I supposed to put all folders through Romvault first? Im so lost. I have searched google, asked on Discords, searched YouTube. Its been like 4 days of trial and error. Any help would be so appreciated 👏
