I have a build for an application framework. Once the build completes successfully I wanto to uninstall the previous version then install the new version . . . automagically!
I can't find any actions for "Add/Remove" or "Uninstall". Does anyone know of a way to do this?

Hi Matt,
You should be able to install/uninstall .msi files by writing some script code using WMI.
[Automise have these actions built in though: Windows Installer - Install, Windows Installer - Uninstall, Windows Installer - Reinstall.]

It’s actually really easy, use msiexec.exe:
msiexec /Option (Required Parameter) [Optional Parameter]
Install Options
(/package | /i) (Product.msi)
Installs or configures a product
/a (Product.msi)
Administrative install - Installs a product on the network
/j(u|m) (Product.msi\> [/t (Transform List)] [/g (Language ID)]
Advertises a product - m to all users, u to current user
(/uninstall | /x) (Product.msi | ProductCode)
Uninstalls the product
