If you are experiencing serious issues with your SOLIDWORKS Electrical software, you may need to fully uninstall the program and all associated programs and files before attempting to reload the software. This document covers how to do this complete removal of the product and associated components.

Before Uninstalling SOLIDWORKS Electrical

Prior to uninstalling SOLIDWORKS Electrical it is recommended to backup your environment and then deactivate your Electrical license. If you are using a network license skip the deactivation process and continue to backing up your data.

Back-up your data

It is strongly recommended that you archive your environment prior to performing any uninstall or maintenance of SOLIDWORKS Electrical. This will save a copy of all your program data (projects, components, symbols, etc.) into one compressed file. To do this, click the Archive Environment button within the SOLIDWORKS Electrical application and run through the wizard. Note that the archive may take several hours to create, so we recommend running this process overnight.
