I am doing a PoC that involves creating an MSI that has version 1.0.0.0; installing that version to a test machine.
Next, I create another MSI (same name, same product code, different package code, same upgrade code). I merely added a single new .txt file to the sources of the original (v1.0.0.0) MSI. I create the new MSI file using WiX and give it version 1.1.0.0.
All good so far.
Here's a breakdown of the codes so far (from Orca.exe):
ProductCode for msi-v1.0.0.0: {CBCF9206-1539-47B8-9A46-A18C2E40D7A1}
ProductCode for msi-v1.1.0.0: {CBCF9206-1539-47B8-9A46-A18C2E40D7A1}
PackageCode for msi-v1.0.0.0: {AB2B02E4-213E-48C1-9394-E30A75BAF2BE}
PackageCode for msi-v1.1.0.0: {C68D3A88-583A-41BF-A971-CB5E083B8547}
UpgradeCode for msi-v1.0.0.0: {06726F10-FF0B-4534-A008-032A70CACDBB}
UpgradeCode for msi-v1.1.0.0: {06726F10-FF0B-4534-A008-032A70CACDBB}
ProductVersion for msi-v1.0.0.0: 1.0.0.0
ProductVersion for msi-v1.1.0.0: 1.1.0.0
What I am trying to accomplish is the deployment of that new single .txt file via this Minor Upgrade. I know that there is a smaller type update called Small Update, but that is not where this PoC is headed. We will need to change the version number as a part of our end game.
I have this in the Wix script that is used to gen both the MSIs (I really don't think this has anything to do with my issue - just including it because it has the word 'Upgrade' in it):
<MajorUpgrade
DowngradeErrorMessage="A later version of [ProductName] is already installed. Setup will now exit."
AllowDowngrades="no"
AllowSameVersionUpgrades="yes"
/>
What I am seeing is that when I run:
msiexec.exe /i FileName.msi REINSTALLMODE=vomus REINSTALL=ALL
I do not get the new single .txt file delivered. I do see that the product version (in appwiz.cpl) changes from 1.0.0.0 to 1.1.0.0, and the cached local MSI file (under C:\Windows\Installer dir) is indeed now version 1.1.0.0 (verified by Orca.exe).
I am puzzled as to why the new single .txt file is not being deployed.
I guess my primary question is: Why won't this Minor Upgrade (i.e. same product code, diff package code, diff product version) deliver the new file?
Thanks in advance for any pointers!
