NHC posted the following instructions to their user group concerning Flash support in viewers. Presumably these instructions would work for other media devices that require Flash support in the viewer:
If you like the old UI like SL or Emerald 1.23, the Emerald viewer 2270 (1.4.0) is a good option for you because it has the same UI of these old Viewers, but it has support for flash player and the Emerald feautures that we love.
PS.: All the steps below apply to Snowglobe Viewer too.
1) First download and INSTALL one of the options below:
