1. Go to Windows Control Panel and select "Programs" and then ”Programs and features”. Select SOLIDWORKS installation from the list of installed software, right-click on it and select the option ”Change”.
2. Select the option ”Repair your installation” and press ”Next” button. Select all the products to be repaired (selecting all products is recommended) and then press ”Repair” to start repairing the installation.
3. Time required for repair installation depends on the amount of repaired products. Furthermore, low disk space, running installation from network drive and real-time antivirus scanning are typically slowing down the repair installation process. But it usually takes around 10-30 minutes to finish the repair process. When the process is complete, press "OK" button.
