I am trying to run Registax 5 under Wine, and I found it encountered a
problem with the stable version. After reading something that said it would work
under 1.1.26, I upgraded my Wine all the way to the most recent version, 1.1.29.
However, this one also has a problem with Registax. It would seem, then, that
there is a sweet spot around 1.1.26 that would work, so how do I downgrade my
Wine from 1.1.29 to 1.1.26?
