AllowSameVersion in Upgrade if the the forth number is higher

[RivkaLeizerson]

I’m using WixSharp for my MSI installer. I want to enable upgrades when:

Any of the first three numbers of the new version is higher than the installed version → upgrade allowed.

The first three numbers are the same → only allow upgrade if the fourth number (revision) is higher.

For example:
AllowUpgrade: 25.2.1.3 -> 25.2.1.4

Not allow: 25.2.1.3 -> 25.2.1.3, 25.2.1.3 -> 25.2.1.2,

How i can do it in wixsharp ?

Not exactly. But not because of WixSharp or even WiX.
Your problem is MSI.
MSI does not support any analysis of the revision number. It just does not see it.

While technically it's possible to create a smart CA that does the analysis manually and performs uninstall explicitly, without relying on MSI services, I do encourage you to reconsider sticking to the 3 components version, since it is the intended versioning paradigm of the deployment technology you are using - MSI.
