[wix-users] .Net Framework install not working

Tue Sep 22 10:26:42 PDT 2015

Thanks for the explanations!  If a program requires .NET 3.5, at least, and Windows 8 and later don't have .NET frameworks installed, what is the outcome of launching such a program and having the .NET dialog pop up?  Does it try and install lowest .NET version that it can (4.0?), or does it simply fail?  By having 4.0 or higher installed, 3.5 .NET programs should run fine, right?

We really need to the bundle log in %temp% to diagnose the issue, but there are some issues with the BootstrapperCore.config.

The host element is used to tell mbapreq which assembly contains your BootstrapperApplication class, you should only specify one host element.

The order of the supportedRuntime elements shouldn't cause your problem, but be aware that by putting 4.0 first that you will be running in the v4 CLR if it's installed.

By leaving out supportedFramework elements, you're saying that the BA can be loaded under the v2 CLR without the 3.5 upgrade.  Since you say your BA requires .NET 3.5, you should add a supportedFramework for 3.5 under the host element.

Finally, be aware that there is no redistributable to install .NET 3.5 on Windows 8/Server 2012 or later.
