Sitefinity_4.0.1133.0

Hi I am attempting to install the weekly build 4.0.1133.0 and I get the attached error. What I first was to un-install Sitefinity of my PC altogether and then I re-installed the latest stable bversion 4.0.1098.0 and then I tried again to install 1133 and still no success.

Can you help?

No worries, I have downloaded the release again and it worked this time. 
Maybe a corruption occurred during download.
Thanks,
Andrei
