4. Can you convert MSI files to EXEs?

We cannot do that here, but there is inexpensive software that will do the trick for you: http://www.cornerhouse.ca/en/msiselfextract.html

It's call MSI Self Extract, and it will turn any MSI file into a self extracting EXE.

You may also want to take a look at MSI Launch, which will let you program your MSI to open your software after the installation is completed: http://www.cornerhouse.ca/en/msilaunch.html

Keep in mind that you will need to use the software each time we send you an update.
