Hi All,

I am developing an installer using WIX Tool Set. One of my requirements is that i need to use same MSI for deploying Multiple Instances on the same machine. I tried to do this using InstanceTransforms as suggested in many articles over internet like as follows:


Revisited: Multiple Instance installations and patches ...<http://sklyarenko.net/blog/2011/09/14/revisited-multiple-instance/>
I initially blogged about multiple instance installations couple of years ago. The way I described it worked fine for me, but the time flies and the …

I followed this article and succeeded in implementing it. It works fine in install and uninstall mode. However, I have issues with the upgrade mode. As far as i have seen Instance Transforms does not allow Major Upgrade. Is there any way to do that?

Also, i have bootstraped my MSI using WIX bootstrapper into exe. But it doesnot supports InstanceTransforms or Multi Instances, Has anyone faced this issue? Please advise any sample solution or web link.
