Hi, I'm currently trying to optimize the MSI generation for our software. Using suggestions found on Stack Overflow I've been able to generate a single project with variable WXI files in order to generate my dev/test/live MSI's (the WXI's simply defining a list of unique component ID's, instance location, etc). I'm now wondering if there would be a safe/predictable manner in which to only generate a single MSI per binary build (and possibly generate a targeted MSI by applying a transform on a release event).
The Wix 3.6 component property MultiInstance seems to be exactly what I am looking for, but I was looking for a sanity check before I go down this road. If I am understanding the bits and pieces I've found, I could create an instance transform for each dev/test/live that would change the product code, upgrade code, instance location, misc UI text, and embed them within the MSI. Then, with this single MSI I could use my boot strapper to apply the appropriate transform. I'm also seeing an InstanceTransforms and Instance element in the documentation, but Instance doesn't allow for specifying an UpgradeCode. Since my need is to provide an updated Develop MSI before test and live, I would need a unique UpgradeCode in order to only upgrade the develop instance without upgrading the others. Would I have to generate a second transform to update the UpgradeCode, or is there a means within the existing Wix multi-instance framework to do so? If this is correct, then can we confirm that the major upgrade, uninstall, and repair functionality would all remain intact? (I would venture to guess the transforms applied to the source database are stored in the registry under the product code.) Would it be possible to deny running the MSI directly to enforce that a transform has been applied? Assuming the structure of the installer hasn't changed, can the transforms be reused for multiple builds of the installer?
