Downgrade patcher cant do its thing

Whenever i run the patcher after unzipping the files into the SP Tarkov folder using 7zip i almost immediately get the error shown in the image. I have played SP long ago and never had this issue so I'm unsure of how to get around this.
Thanks for any help in advance.

Lol so i deleted everything Tarkov and reinstalled it again and it worked this time round after checking integrity and everything else I could think of.
