I have the unregistered version of fsuipc. i've read that you don't need the registered version for most add-ons. trike-immersion and precipitfx seems to work fine, but the 737 immersion does not. i don't see any change in lighting, and no wing/engine condensation either. does the 737 immersion require the registered version of fsuipc or is there something else that might be the problem? 

Hi,

 

They all work under the same logic.

 

Are you using FSX or P3D?

DX9 or DX10?
