Build myself a wee little outlook add-in based on the VSTO model. Works nicely. But now I'm looking at deployment. The first time I deploy the add-in it installs fine, and everything seems hunky dory.
I then make a change to the application. Some of its DLLs remain the same, others are changed. So I recompile the Solution, I increment the Version number in the deployment project, which prompts me to change the product code (which I do) but that leaves the Upgrade Code intact (ok...). I set RemovePreviousVersions to True ...
And it installs the newer version fine. But now it doesn't run.
So I set RemovePreviousVrsions to False
And it still installs the newer version fine, but now there are TWO entries for my product in Programs and Features.
Neither of which are acceptable. What am I doing wrong?
