Make sure it installs properly on any well working system

I tried several times to download and install it, but was unable to install it since it
1. got an error for there was no dvdmmg.sys in the temp folder
2. asked for inserting a Photogallery disk in my CD Drive looking for Photogallery.msi
Then I entered the wrong code, but I did not write down the activation code and then the site was for this was no longer available, though there was still one hour left to activate it.
