As I said before, you are missing files under the /Setup folder, specifically you are missing files under
/Setup/applications/blog/SchemaUpgradeScripts/mssql
so no matter whether you extracted the files on the server or not, there are files missing in your installation that do exist in the mojoportal-2-4-0-0 package.
You should restore the missing files and visit the setup page again.
There should be files incrementally from 2.6.0.0 up to 2.6.1.4 for the blog that are apparently not there so the setup page can't run them
Hopefully there are no other missing files elsewhere, if you encounter further errors then I will suspect there are other files that did not get deployed.
