Plan B for Spectragryph

I have spectragryph (hereafter called "gryph") installed on my windows machine. On my machine, it is installed at: 
C:\Program Files (x86)\Spectragryph 1.2
Of particular interest in this directory (folder) is the file: 
TurboActive.dll
We will talk about this file more in a minute.

When I launch spectragryph, it gives a splash screen telling me it is version 1.2.16.1 When I click on "About" on the left, it tells me it is currently running in trial mode, not licensed.

Implement plan B

Plan B involves replacing TurboActivate.dll (and libDecryptLibrary.dll) with a more permissive version.

You will need to somehow become the administrator to do the following. What I do on my machine is to right click on the Start menu "icon" to get a menu and select: 

Windows PowerShell (Admin)

Then I do this: 

cd C:\Program Files (x86)\Spectragryph 1.2
mv TurboActivate.dll TurboAct.OLD
mv libDecryptLibrary.dll libDecryptLibrary.OLD
copy \users\tom\TurboActive.dll .
copy \users\tom\libDecryptLibrary.dll .
Now when I launch Spectragryph, it tells me it is activated with a valid key, and the "About" tab on the left shows the key as blank.

Of course you should be wondering where to get this more permissive version of TurboActivate.dll. Try installing these two. The pair will also activate ThunderOptics spectrometer support:
