Hi
I am a bit rushed just at the moment so have not executed a full deploy of SilverStripe using the new archive.
What I have done is unzipped the two archives (the .tar.gz and the .zip version) using the same version of WinZip (12 I think) that gave me problems before. The .zip version had the correct file extensions in the \framework\thirdparty\zend_translate_railsyaml\library\Translate\Adapter\thirdparty\sfYaml\lib area, the .tar.gz version did not. So I am pretty confident the .zip version would work.
I am also pretty confident it is not my old version of WinZip, I had upgraded that to the latest version whilst I was having issues.
So good to have found the issue I think. There are several other forum threads that mention this so people have been struggling. I'm not sure whether you could link those threads to this one. The first error you see is the absence of the PHP files in the directory I mention above. People then correct that manually and may get to the almost working state described by myself and Ben.
The new download link will really help of course.
Thanks. And if you want me to check anything else out let me know although it will likely be next week
