New Post: Depedent DLL

In my setup, there is a requirement to install a license file into a license store. The function depends on a number of dll which are installed during the setup.

My questions are:

1/ is the dll available during elevated custom action, that is, do I have to explicitly tell wix to load those dll into a temp location
2/ All the files in the installdir are not visible until the setup is finished. How does one go about loading a license file during custom action.

Thanks.
