For those who find the process of installing on new computers and having to run setup ,etc,etc. Here is what I have come up with as a simple method:

Note: if you want to have uninstall ability this won't work...

1. Move the dll to appropriate place
2. Create a .reg file with following lines:

Windows Registry Editor Version 5.00

"Value3"="E:\\samples\\Atmosphere\\Atmosphere Data\\Atmosphere.dat"

The dashes above are not part of the file, it is just to show you what it will look like. Specify your file location and be sure to use double backslashes or it won't work. Give the file a .reg extension. Then right click the file and select Merge.

Done. No more worry about Spectramove utility, etc, etc.

Works with Trilogy of course as well.
