Cadsoft has released a c3 update to version 15 that addresses some issues.

The update can be installed in one of two manners:

  1. If you currently have c2, you can install the update as a patch. In Envisioneer, go to Help>Check for Updates. This method will leave your catalog intact.
  2. If you are on c1 or have yet to install v15 you must do a full installation by using the download from this link: https://envisioneer.s3.amazonaws.com/Envisioneer_15_C3_Setup.exe This method will overwrite what is currently installed. You will need to back up personalized catalogs. Please read this bulletin: https://www.cadsoft.com/learning-center/support-learning/installation/saving-before-uninstalling/ 

If you are not sure what version you have, in Envisioneer select Help>About. The version will be published in the lower right.
