- Close all running versions of the software
- Download https://envisioneer.s3.amazonaws.com/InterprocessServer.exe
- Copy the downloaded file to the following folder: C:\ProgramData\Cadsoft\InterprocessServer
- Restart the software’s earlier version, and the billboard plants will be visible again.
Please note that if you then use V16 and later versions, you will need to reinstall to use 2D plants. The above executable will not work with V16 and later versions. You can either have 2D plants in one version or the other because of the nature of the change to the executable file.
Please also note that the 2D Plant library is being phased out and replaced with more attractive and functional 3D plants. Therefore, moving forward, the 2D plants in earlier versions will eventually become unsupported.
