IFC File Double-Click Issue
When you install an upgrade for Simplebim it can sometimes happen that double-clicking on an IFC file in the file system starts the Simplebim installer. In this case importing an IFC file requires administrator rights.
This is typically associated with using the automatic updates feature in Simplebim. We are working on solving this issue, but the current fix is to first uninstall Simplebim and then install again using the Simplebim installer that you can download from the Simpelbim site. Re-installing Simplebim does not affect your license or the settings stored in your user profile.
