Hello,
I just downloaded and installed my Envshade and Envtex purchases from SimMarket, and made sure to run the P3D version of the installers, as well as the relevant patches and expansions available as download from SimMarket, in Administrator mode. After choosing my settings and selecting install to sim, I got the following error:

I am on P3Dv5.1.12. Is my version not compatible with the current version of Envtex and Envshade?
The latest patch has probably not been installed or something went wrong somewhere because 5.1.12 is totally compatible with Envshade. Could you please try to run Envupdater from Envdir and install the latest version again?
Thank you for the reply, and I have not seen the error since running an update within Envdir. Its weird because I thought I ran all the patches that came from SimMarket. Do you think that this error will cause any issues with my sim down the line? Do I need to reinstall P3D or clear cache or something?
