Checking for .NET installed in WiX installer? Where to place the condition?

Question

I need to check for .NET version 4.5 installed before proceeding with my installation. This is my .wxs file. I've placed the propertyref and condition under the tag. Why is this check is not working?

Even if .NET 4.5 is not present on the target system, the installation goes ahead anyway.

That looks OK so you probably also need to:

"Add the -ext command line parameter when calling light.exe to include the WixNetfxExtension in the MSI linking process."
