.net CORE 1.0 won't install on VS 2015 w/Update 3

Question

Just updated VS 2015 To Update 3. Completed successfully. Then tried to install .Net core 1.0.0, which failed, saying that Update 3 didn't appear to finish and to repair it.  If I rerun the Update 3, there is not repair option and the install looks fine to me.

The last two lines of the core log file look like this:

[06F0:0418][2016-07-22T16:19:13]e000: Setup has detected that Visual Studio 2015 Update 3 may not be completely installed. Please repair Visual Studio 2015 Update 3, then install this product again.
[06F0:0418][2016-07-22T16:19:13]e000: Error 0x81f40001: Bundle condition evaluated to false: WixBundleInstalled OR NOT(((VS2015CommunityUpdateVersion <> VS2015UpdateVersion) AND (VS2015CommunityExists) AND (VS2015UpdateVersionExists)) OR ((VS2015ProfessionalUpdateVersion <> VS2015UpdateVersion) AND (VS2015ProfessionalExists) AND (VS2015UpdateVersionExists)) OR ((VS2015EnterpriseUpdateVersion <> VS2015UpdateVersion) AND (VS2015EnterpriseExists) AND (VS2015UpdateVersionExists)) OR ((VS2015WebExpressUpdateVersion <> VS2015UpdateVersion) AND (VS2015WebExpressExists) AND (VS2015UpdateVersionExists))) OR (SKIP_VSU_CHECK=1) OR (WixBundleAction=2)
[06F0:0418][2016-07-22T16:19:13]i199: Detect complete, result: 0x0

Any help would be appreciated.

Answer 1

I wonder if this has something to do with the C++ redistributable.

This page (which is pointed to by the .net core "simple" installation page) https://github.com/dotnet/core/blob/master/Documentation/prereqs.md#windows-dependencies gives a link to install c++ redistributable version 14.0.23026.   If I try to run that, it says there's already a different C++ redis. already installed. If I look, I see have several versions, going up to 14.0.2412, which appears newer than the one in the link above.

So is it possible my installation problem is that I have a newer C++ redis. than the setup for .NET Core is looking for??

More information.

This page: https://www.microsoft.com/net/download

Shows more options for installing .NET core. I downloaded and successfully installed the .NET Core SDK Installer (Preview 2) for X86..

Hmmm.  Why would that one install by the supposed "simple" installer they recommend fail??

We're not off to a good start on .net core :(

Answer 3

Crud.. the next step, insalling .NET Core for Visual Studio official MSI Installer.  Also ended in error, just like the original .NET core did.

Something is still not right..

And this is a C# issue?

Answer 5

I was able to install it by running with SKIP_VSU_CHECK parameter

DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1

Wow ty. That did the trick lost almost 3-4 hours from work time repairing VS.

Answer 7

Wicked Pixel's solution to install

DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1

did allow me to install that product, but still when I start VS 2015, there is no option to create an application based on .net core.

WTH ??

Hi,

Thank you for posting here.

>>there is no option to create an application based on .net core.

If you can create a c# project, actually you are using .NET core.

The .NET Framework is a managed execution environment that provides a variety of services to its running applications. It consists of two major components: the common language runtime (CLR), which is the execution engine that handles running applications; and the .NET Framework Class Library, which provides a library of tested, reusable code that developers can call from their own applications

If your issue has been resolved, please mark it. I hope the reply can be helpful to you.

Best Regards,

Hart

> Setup has detected that Visual Studio 2015 Update 3 may not be completely installed.

This says it all, what you can do is try to repair the Visual Studio. You can get that link from Control Panel, under the Change options you will find "Repair" along with Modify and Uninstall. Click on Repair. 

What this will do is, it will try to fix most of the Visual Studio settings and will see if there are any packages that are required to be installed on the machine in order to let Visual Studio (and child platforms) work. Then you can continue installing the packages for .NET Core.

Answer 10

I did try to repair, that doesn't help.

 Condition NOT(((VS2015CommunityUpdateVersion <> VS2015UpdateVersion) AND (VS2015CommunityExists) AND (VS2015UpdateVersionExists)) OR ((VS2015ProfessionalUpdateVersion <> VS2015UpdateVersion) AND (VS2015ProfessionalExists) AND (VS2015UpdateVersionExists)) OR ((VS2015EnterpriseUpdateVersion <> VS2015UpdateVersion) AND (VS2015EnterpriseExists) AND (VS2015UpdateVersionExists)) OR ((VS2015WebExpressUpdateVersion <> VS2015UpdateVersion) AND (VS2015WebExpressExists) AND (VS2015UpdateVersionExists))) evaluates to false.

For some reason VS2015UpdateVersion is less than the other Update Versions, so it fails to see that update3 is installed.

For example:

'VS2015UpdateVersion' to value '14.0.25420'

'VS2015EnterpriseUpdateVersion' to value '14.0.25424'

Was able to work around by skipping update heck like suggested above. Thanks!

Answer 11

Thanks alxdjo! Seems to work. I just wanted one day where I get to work without doing any workarounds, just one day. Cheese sause crust. Xamarin dev for android is already a workaround built on top of semi baked hack called java. I'm begging MS. Just one day.

Answer 12

It's running. Thank you so much!

Answer 13

Thank you! I re-installed VS like 2 times an still didn't work. Clean solution in your answer :)

Answer 14

same error and impossible to modify/repair vs2015 update 3 as it is correct.

by despair I run:

vs2015.3.exe /force

then I get a strange version of vs: version 14.0.25123.0 D14REL

from this point I can install DotNetCore.1.0.0-VS2015Tools.Preview2.exe with no error.

My old projects (previous version of .net core) still build, yeoman runs, and dotnet.exe --version gives the expected version.

Answer 15

It's worked for me.

Just have to note that I had to install the 

DotNetCore.1.0.0-VS2015Tools.Preview2.exe

twice: Once with this vars and after that as a regular setup (without the var: SKIP_VSU_CHECK=1).

Answer 16

I am facing the same issue and came to this post after a few bing.

Might be a dumb question but where exactly I should run this command:

DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1

Hmm, got it.. Run the command from VS command prompt from the folder where you have your dot net core installer.

Answer 17

Thanks and this works

DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1
