Last week we released visan 4.3.
With this release, visan is now available as a package on conda-forge itself. This means that you should no longer use the stcorp or stcorp-forge channels to install visan.
To install visan you can now use:
conda create -n visan
conda activate visan
conda install -c conda-forge visan
This release should also solve the issue with starting visan as was raised by other topics in this forum.
