I have created an Installing using Wix 3.6. I then created a bootstrapper exe to do a pre req check for .NET then kick off the main install.
When the main install pops up (full gui) and you click to Install it, the progress bar progress does not progress, it stays "blank" just the action text changing gives you an indication that it is doing something... attached are the log file from the bootstrapper and the main install...

Managed to create a repro even earlier. Attached BundleTest.zip contains solution with 2 projects (MSI and Bundle). When running bundle, you will see that progress bar of MSI doesn't move.
Also added video screening of the case - see screen.avi file inside the zip
