I have a version that's several years old. It's slow, and quite often it won't open a Microsoft Office document, which is why I bought it. I'm willing to assume that the new product is much better than mine, but there's no discernible upgrade pathway from a prior version, and there is absolutely no way to contact anyone at the parent company, by email or telephone, even if you're willing to pay for the privilege. With just a touch of effort by this company, which another $10 added to the purchase price would probably fund, this could probably be twice the product it is.

I've "recommeneded" ThinkFree Office because of its price, and I still may buy it to try out the new version, but it's like ordering something at a post office office box number off a TV add. Their effort to avoid you is obvious.
