Welcome to our community.
I'm assuming you have perused the gallery of skins that have been included in RoboHelp? And assuming you have, have you looked at the gallery at the link below?
If you don't see what you want in each of those places, it hasn't been shared with the world. Can you point us to an example of what "VMWare" looks like?
Helpful and Handy Links
It looks like a lot of what you have in the VMWare skin could be achieved in RoboHelp. From the image you posted it looks like there are mail and print icons on the right. You could set these up in RoboHelp as cusotm buttons although they may not appear in the same position. The other buttons look like navigation buttons but without details of what they navigate to, it hard to say what you could do in RoboHelp. If they are just back / forward buttons to last / next topic this is easy to achieve. The rest of the look and feel of your skin should be also easy to achieve. Just find a skin from the link Rick posted that best matches your requirements and change accordingly.
