Uninstall should check that ProductCode is installed on TargetMachine before calling msiexec /x


When using the Uninstall task directly (rather than through the Deploy task), it executes msiexec /qn /x ProductCode. This fails on a machine that does not have the product code installed. This is because msiexec throws up a message box saying that you can't uninstall something that isn't installed. With quiet mode, this just fails.
For a team build scenario, there are often times when a new build/product comes along. When the process attempts to install the msi the first time for a target machine, the build will always fail. I think this activity should use similar logic to Deploy where it resolves the ProductCode from a ProductName. The Uninstall task should search the target machine registry to see if the package is installed before calling out to msiexec /x.
The next time a build kicks off, the package is installed, the product code will be in the registry and the uninstallation will then be invoked.

added check in Deploy activity to only uninstall if the product is installed on the target.

Great suggestion! I agree this is the way it should work. I'll get this implemented in the next release.
