Activation problems after rolling back to P3D V3.3.5

[YRZHOU]

Hello Virtuali:

Happy New Year! I recently rolling back to V3.3.5 from 3.4 due to some CTD issues, And trying to reinstall the FSDT products starting with GSX, however getting an esellerate error (code:0xe0010004) with the description: No engine is installed.
Because currently I am not flying in the US, haven't try to install other FSDT products yet,  but expecting same problem there. the installers were pretty new, I think I download them two weeks ago.

Regards
YRZHOU

IMPORTANT: This update requires downloading the latest GSX Full installer from the FSDT Website.
