Dear d.s.account,
"The ViennaRNA Package consists of a C code library and several stand-alone programs for the prediction and comparison of RNA secondary structures".
You seem to have correctly installed a pre-compiled ViennaRNA package for a 64-bit windows machine. You need to know however, that ViennaRNA is a command line-based (see https://www.tbi.univie.ac.at/RNA/documentation.html#programs) and hence, it has no graphical interface.
To run a given program you will have to open the windows cmd and launch commands on the terminal. Try for example opening the command promt (to find it, write cmd in the windows start button). Then run:
AnalyseDists
AnalyseDists is one of those random programs. Without arguments, it should give an error from AnalyseDists. If instead the command promt says something like: "'AnalyseDists' is not recognized as an internal or external command", then, ViennaRNA has not been properly installed.
Most users in bioinformatics will be very familiar with Linux shell. Windows is often avoided. So don't expect too much help on the Windows command line here. Other than that, you can read the documentation of the individual programs and ran them as above.
Good luck!
Ventrilocus.
