MSI and File Versions

Got stung again by File Versioning in MSI. If the file version in the installer isn't greater than the file version on the server, the file will not be reinstalled. I thought the File Version property in the project properties set this version for files, but apparently it does not - so my file changes are not being deployed, even though I am continuously incrementing the File Version property.

So what I found was the REINSTALLMODE option for msiexec. Installing the MSI like this did the trick:

msiexec /i <MsiName> REINSTALLMODE=a

Here is the list of REINSTALLMODE options.
