ASP.NET 5 Beta 8 cannot install in visual studio 2015

Question

I currently have Visual Studio 2015 Enterprise. I previously successfully installed the beta version of ASP.NET 7 using the same method that I am trying to install Beta 8.

I used the method described in the BETA 8 manual.

1. Close all instances of Visual Studio.

2.Install the .NET Version Manager (Beta8) using DotNetVersionManager-x64.msi. For 32-bit machines, DotNetVersionManager-x86.msi is used.

3.Uninstall Visual Studio 2015 using ASP.NET and Web Tools 2015 (Beta8) by installing WebToolsExtensionsVS14.msi. If you are using Visual Studio 2015 Express for the web, then install WebToolsExtensionsVWD14.msi instead.

In the third step, when you run the WebToolsExtensionsVS14.msi installer, the following error message appears

This product requires Visual Studio 14. "Install Visual Studio 14 then try installing this product again."

When I open Visual Studio, it shows that I have version 14 installed

Then I uninstalled beta 7 by running the uninstaller and trying to install beta 8, and I still got an error.

My question is: How to install ASP.NET Beta 8?

Answer 1

Decision. You need to run the MSI package as administrator.

I was able to install it by opening a command prompt as administrator and then running msi directly.

As an alternative, you can also add the option “Run as administrator” to the parameters of the right mouse button by changing your registry. Link
