Hello InVEST users,
We are currently experiencing an issue with our Windows certificate. This means that downloading and installing InVEST will likely bring up a big red UAC message blocking the installation process. We are aware of the issue and working on it! Hold tight and we’ll let you know as soon as we have things back in order.
If you already have InVEST downloaded and installed then you are good to go ( just don’t uninstall it! ).
