Starting from SOLIDWORKS 2013, the application SOLIDWORKS Launcher is used to open files using the appropriate version of SOLIDWORKS, if multiple versions of SOLIDWORKS are installed. Some users find opening a file by right clicking on the SOLIDWORKS file and selecting Open from Windows Explorer or double clicking on a file results in multiple instances of SOLIDWORKS opening up. This issue occurs if the SOLIDWORKS file type is directly associated to a specific version of the SOLIDWORKS executable application, instead of the SOLIDWORKS Launcher’s executable application. The following article discusses how to resolve this anomaly.
Associate Files to the SOLIDWORKS Launcher
To re-associate the files to the correct executable application, please follow the instructions below.
