The program will run direct from the CD for you to try it out. If you decide to install it on your hard drive it also requires a copy of the VBRUN300.DLL runtime module, which is in the software\hound\product directory.
The installer does not install this file by default as most people already have at least one copy of it, but if you haven't you can simply copy the file to your windows\system directory.
You only need one copy of this file which can be shared among all your programs if it is in the windows\system directory, and Space Hound Pro is the ideal tool to find all the extra copies that are littering your hard drive and just eating space!
