Does it tell you what the missing DLLs are? If they are something like the VB runtimes they are available multiple places around the net, including straight from Microsoft. I've used a number of programs in my time that required me to pull down a DLL or two from the net. Adding DLLs is one thing, if something is prompting you to replace your DLLs with a different version be very careful about this. You can screw up your Windows install.
