Inno Setup "Cannot import dll" (IS v6.2.0, TA v4.4.4.0)Solved

I've gotten TA working in my main application and am looking to add it to the installer/uninstaller as a convenience for the user and so that I can look at license fields during install. 

I've added the example and followed the guides, and it compiles fine, but when attempting to start the installer I get an error:

Runtime error:

Cannot import dll: <utf8>C:\users\[temp path]\TurboActivate.dll

If I browse to the path I can see both the .dll and DAT are present. Placing TurboActivate.exe beside them it is able to launch and interact with the license so the DLL/DAT is not corrupt.

The debug output says:

[16:31:22.435]   Importing the DLL function.
[16:31:22.444]   Failed to import the DLL function (193).

There is no longer a non-unicode version of Inno Setup, so I know that is not the issue (I've seen that brought up in previous topics asking for help with IS). 

Thanks for any insight!
