Subject: Question regarding versioning and replcements.
Hello eveyone.
This is probably a silly question, but here goes.
When buiilding MSI in Visual Studio, I get a guid for versioning. (Version 1)
Then later when I rebuild the project with a new version, (Version 2) I get
a new GUID.
When this is distributed to my Clients, everything works as it should.

Now suppose I rebuild one more time with a new version. I get another GUID.
(Version 3)
Suppose I send this off to a Client who has not installed Verion 2. When
they try to run the install, it fails.
Can I somehow specify to remove any previous version and install the newer
one?

Thanks,

I assume the guid you're referring to is the ProductCode guid. I say this
because there are guids everywhere in MSI, and it's possible you mean the
UpgradeCode guid or something else entirely!

I think RemovePreviousVersions is what you should look at. That's what
removes older versions of your product.
