Just a quick note that the standalone version has a number of bugs (e.g. plugins might not install, templates might not install, etc.). So if you get an error, try the Firefox based one which works very well.

There's a newer version (1.3.4 vs. 1.0.6/1.1rc2) at http://pencil.evolus.vn/en-US/Downloads/Application.aspx

I don't know if it fixes any of the problems deyan mentions (or which version he used), but 1.3 is about 2 years newer than the version on their older site. They really should delete the old copy of their website's URLs, and redirect to their new site.
