Installation Error Needs Help

I downloaded the ojs-2.4.6.tar file, using 7zip I extracted it, zipped
it and uploaded to a folder on my website. I then unzipped and
everything was fine. I got everything ok but cant go past the first
page. Despite all the details I filled in to ensure database works but i
keep seeing the error message “Fatal error: Class ‘DOIExportPlugin’
not found in
/home/theloveo/public_html/ijavs/plugins/importexport/medra/MedraExportPlugin.inc.php
on line 27” The error_log file has the same message. Need help to fully
instal ojs. I am running PHP 5.4.36

Thanks @asmecher,
I tried using tartool but got the same result. Now I am trying to give winrar a try. I hope this works as it is becoming annoying. Thanks for the response
