If you have an HTC EVO 3D, and have had some issues flashing the TWRP (and be sure to check out Josh's awesome hands-on and interview with developer agrabren) while using version 1.5 of hboot, our own AC Developer scrosler has whipped up some badassery to help you along. It's a Windows only tool, but all you need to do is install the USB drivers, and click the button to get TWRP flashed and running. While it works for all versions of hboot, it was designed for and tested with rEVOlutionary S-OFF 1.4 hboot, and 1.5 hboot unlocked with HTC's unlocking tool.
As always, the best part is the level of support you get. The forum thread is right there, and scrosler is an active member of the community as well as a developer, so you can feel at ease giving this one a try -- we all weren't born with a working knowledge of the command line. This is why we love our AC Devs. Not only do they cook up awesome hacks and tools, but they stand behind them. So if you've been waiting, head into the forums and have a look.
