Hi,

I am starting to use Burn as a bootstrapper around our product's msi and a
few dependencies.

I can at some DetectConditions for checking whether the dependency is
already present on the pc.
I started with a Util:RegistrySearch, which is working fine. I would like
to add another variable based on a filesearch, but this filesearch should
check for the filesize aswell.
The Util:FileSearch does not offer a filesize condition.

Previously we created a property and used FileSearch directly (not the util
version), which offers a Min and MaxSize attribute.
It seems that the property is not invoked before the DetectCondition.

1. Is there a way to check an existing file including it's size, for the
DetectCondition of an ExePackage?

2. If a dependency is already installed, but is not the correct version. Is
it possibe to run a local executable (the uninstaller on the end users pc)
before starting an ExePackage?

Cheers,
Tommy
