updating Sourctree to 2.5.5 .NET installation failure

When updating Sourctree to 2.5.5 the installation requires .NET Framework 4.7.1. When I install that, I get the folowing error and cannot continue the update or run Sourcetree: "not supported on this operating system."

I am running Windows 10 Enterprise build 10240 64bit and.NET Framework 4.6.1

Problem solved, Windows updates needed to be installed first. Thanks.

That did not solve it for me.

Thanks for getting in touch. It appears the issue is explicitly to do with this specific version of Windows 10:

Windows 10 Enterprise 2015 LTSB. Version 10.0.10240 Build 10240

Also know as 1507.

It appears 4.6.2 is supported but not 4.7/4.7.1. We will investigate what we can do about this.

It appears the only security updates will be available for 1507 going forward.

The newer LTSB version 1607 does support 4.7.1.

For now I'm afraid you will have to re-install which is available from here: 

I get a 404 on that page

cut'n'paste error its correct now.

As is this copy

I'm in the same situation: Windows 10 Enterprise 2015 LTSB. Version 10.0.10240 Build 10240.

But I can't run Windows Update, nor can I install .NET 4.7.1.

I had the same problem, basically an overzelous IT manager decided to make all workstation images default to LTSB. 
If you can do an in-place upgrade to 2016 LTSB, that works and allows .net 4.7.1 (skipped right to 4.7.2 actually). May not be possible in your scenario though.

Arouse naturally recognizes close by systems and hotspots that communicates their system name. In the event that you visit puts that offer access you can set up your system or enter secret word if necessary for your set up.

I'm in the exact same boat. Can't install, can't run. I have to roll back to v1.x.

Same issue for me. Using Window 10 Enterprise, version 1511, build 10586.1295.

The same problem, it's outrageous! it's easier for me to switch to another program than to update the Windows, because 4.7.1 can not be installed!

Please reboot to make sure .NET 4.7.1 is picked up by the OS.

Thing is, the .NET installation does not complete due to the error.
