VB 2010 require a certain level of .net to be installed? I've not messed with VB stuff in like, what since 2002 maybe, and mainly because everything went from VB6 to .net based stuff. I can't tell you about the errors, better to google for that, but make sure you have all the dependencies ahead of time. With anything VB related, half of all the old errors I ran into were missing runtimes or libraries, or you needed the latest update, ie:.net 4.0 vs .net 2.5 for example but I am not saying in your case that is the issue, just something to think about.

I would start here first - http://webkitdotnet....ge.net/reqs.php then start googling for specific errors, and if they have any kind of return codes try digging them up specifically.

if they come with a basic example form or "hello world" example, try seeing if that works first. If it doesn't, then something probably isn't installed that is required.
