[wix-users] upgrade NOT detected

[Roni Fuchs]

Hi everyone,

We wrote an upgrade (major) to our product, and for some reason on one of the machines the upgrade was NOT detected:
Why could this happen?

It's worth mentioning that we use burn to bundle our products with a couple of prerequisites and to use an MBA.
One of the prerequisites is .Net 4.6.1 which requires a restart before the MBA is started.

No WIX_UPGRADE_DETECTED on the bad machine. Why could this be?


Thanks,
