Hi John,
I have a similar approach of automating the install of a our development
builds into the test environment.
To do this I rely on the msi minor upgrade process. This requires the
following Properties change / stay the same between two revisions of the
MSI.
UpgradeCode stays the same
ProductCode stays the same
PackageCode changes
Version Changes
I would suggest you make the following changes - don't use * for the
product code so that it does not roll each revision and change your
versioning (I use a global build number in the third digit of the
version).
Then all you need to do is invoke the install as a reinstall - ie
MSIEXEC /I <msiname> REINSTALL=ALL REINSTALLMODE=VOMUS

Subject: [WiX-users] How to automated uninstall?
I'm wondering if anyone's run into this before and has a "best practice"
solution.
The scenario is an automated deployment environment that attempts to run
a scheduled upgrade of minor revisions of a product.
Therefore the numbers of the currently installed and to be installed
versions only differ in the revision position.
The major/minor/build positions are identical. This leads msi to not
perform the install as it only looks as far as build to determine
difference.
The first reaction to get around this is to try uninstall/reinstall
instead of upgrade, however uninstall seems to require either the
original msi file (no longer present) or the ProductCode.
Being a good wix citizen I have set my <Product Id="*" .../> which means
new ProductCode for every build and makes it hard to script uninstall by
ProductCode.
Is there a way to achieve the unistall that I'm overlooking? Getting the
build portion of the version number changed is beyond my control and
even new minor revisions do need to be deployed for testing.
thanks
