Ok, so I went and check this thread after I got that fatal error message
http://forum.joomla.org/index.php?topic=50129.msg303825Turns out I solved it by changing my 'unzipping' process a little, seem to solve the corrupted file problem, and solved my initial problem as well!
What I did different
problematic method:
zip app: LzArc 3.5
from the zip window, I selected all files and dragged it into my desired directory. Voila, installation was ok, BUT I had problems accessing the index.php main page.
Ok method:
zip app: Lzarc 3.5
using the same zip client, I extracted all files to another directory, and there was this file that was 'duplicate', selected overwrite (see attached capture)
Voila, everything went through smoothly.
Conclusion? Some corrupted files in the unzipping process?
Hope this helps.
I'm done for now.
