Rebuilding something (usually) makes it different. Look at your BundleCode, ProductCode and PackageCode.

Subject: [wix-users] Bootstrapper not detecting already installed msi package

Hi everyone

I'm trying out the wix tool set and working on a small sample that includes bootstrapper bundle which installs the samplefirst msi from tutorial.
On my development pc I have visual studio 2013 and the wix tools v3.10.

The problem I have is that the bootstrapper does not detect that the msi is already installed on the test system when I rebuild the bootstrapper, even though I haven't done any changes in the source code. This happens for instance when I check out the sources and build them.
Otherwise if I use the same bootstrapper without rebuilding it will detect the product and show the options Repair / Uninstall.
If I try the msi, rebuilt or not, it always detects the product as installed and it won't allow the installation.

As the result when I reinstall the bootstrapper twice I get two applications with the same name on the test system. I see the two products installed in add/remove programs tool.

Source code is attached.

Has anyone an Idea what I can do to solve the problem?

Best regards
