I've got the same problem. Regardless of installation media, Webmatrix or Web Platform Installer, it always fails. Running Server 2012 R2 Standard, Build 9600.

I have same exception. Also I noticed that I can not open this link in IE, but in another browsers it loaded fine.

Thanks Jan. "right-click the folder in which you unzipped Umbraco, choose "Open as a Web Site with Microsoft WebMatrix"" this is what helped me

Hi Aleksey

That's good to hear - Excited to hear from the other guys to see if that helped them as well.

If you're having other issues etc. don't be afraid to post them in here - we're a friendly bunch of people who loves to help each other out rather than flaming each other :)

Cheers,
Jan 

Hi Jan & others,

Thankx for your help. I wil give it a new try on another computer. I did'nt lose my temper, but lost some energy after trying to install it on different ways. Eventhough I still do not understand why installing with Webmatrix or 'Web platform installer' is not possible.

Nevertheless, I will give it a new try. Or will use the manually way.

Thanks! Adrey

Hi Adrey

Happy to hear that you did not loose your temper and that you're willing to give it another go :)

Sometimes the issues can also be permission related, which is also mentioned in the linked documentation.

But give it a go and keep us updated with your progress. If you're still stuck lets take it from there.

Cheers,
Jan
