Aspnetcore: Error while installing ASP.NET 5 RC1 Update 1 on Win Server 2012 R2

[Brij-Mishra]

I am getting error while installing ASP.NET 5 RC1 Update 1 on Azure VM. It has following OS other related software

1- Win Server 2012 R2 Datacenter
2- VS Enterprise 2015 update 1 (installed last)
3 - SQL Server 2014 SP1

Log files shows that it is not able to download DotNetVersionManager_x64 from https://go.microsoft.com/fwlink/?LinkId=708515. However, when I try from browser, it is downloading the msi. The error start as

[1124:12AC][2015-12-20T19:10:08]w343: Prompt for source of package: DotNetVersionManager_x64, payload: DotNetVersionManager_x64, path: C:\Users\WinS12R2Brij\Desktop\DotNetVersionManager-x64_rc1.msi

Looks like somebody also logged similar issue but in different environment configuration. But after acknowledging the issue, no update for last 10 days.

Log file attached.

I tried many ways but no luck. Is it fixed now or any other workaround please?

Had the same problem today. I used the following workaround:

At the end of the log file there are messages with a link to "go.microsoft.com" like this:

[1270:0CC8][2015-12-21T18:15:47]e000: Error 0x80072f08: Failed to send request to URL: https://go.microsoft.com/fwlink/?LinkId=708515, trying to process HTTP status code anyway.

Go to the link (in this case: https://go.microsoft.com/fwlink/?LinkId=708515), download the file, install it, and rerun the "ASP.NET 5 RC1 Update 1" installer.
I had to repeat this step three times with three different files until the installer ran through fully, but this might be different for you. Hope this helps.

@KoesterD Thanks for the workaround. I also had to install three different files to get it worked. Thanks again. Hope ASP.NET team would publish this workaround and fix it soon.

Hi @Brij-Mishra ,

Try to disable Internet Explorer Enhanced security. It worked for me. You can do it via powershel. Take a look at this StackOverflow post:

Best regards Martin

On Windows 7, I'v got the same error.I tried the fixes suggested above, all didn't work for me.

By chance, I turned on a network agent, finally it run a successful install. (PS: The network agent is used to visit some website like google, facebook, twitter etc. in China. Hope this helps Chinese developers.)

On Windows 10 I've got the same error. What does help for me:
In Internet Explorer click on the "Tools" button on the menu and select Internet Options. Select the “Advanced” tab and all the way toward the bottom you will see the option for "warn if changing between secure and non secure mode". Uncheck the option.

I was also dealing with error 0x80072f76. The comment from oahrens to uncheck "warn if changing between secure and non secure mode" in Internet Options -> Advanced tab worked for me.

However, I am not on Windows 10 but still on Windows 7.

Thank you!!

The solution from @oahrens also worked for me. Thank you!

I have checked this in Windows Server 2008 R2 .
In Internet Explorer click on the "Tools" button on the menu and select Internet Options. Select the “Advanced” tab and Uncheck the option. "warn if changing between secure and non secure mode".

@oahrens - Thank you

We moved away from using the FWLINKs that used HTTP and redirected to HTTPS in RC2. But RC1 is a shipped product so we can't change that.
