What will be the possible switches for Talisman (theme) ? I am getting the attached screen during registering components session. Theres no possible switch given for such kind of setup i haven't seen it in the guide.

I'm not familiar with the software you're trying to install, but a quick Google shows that some of our members are using it. They might come through for you yet, so hang in there

If all else fails and you don't get any response, you can always write a short little AutoIt script to install this software for you. Check out the AutoIt site if you want to go that direction.
