I was just using it last week. I select the SimulationXpress icon and I get this error.
It's not listed in my add-ons
Anyone have a quick solution?
If you are using SOLIDWORKS 2019 SP1 or earlier, this could be the following known issue that can occur due to conflicts with some third party programs and Add-Ins:
SPR 949838 - "SOLIDWORKS Simulation: Message '[Sim install folder]\cosworks.dll cannot be loaded. Either the Add-in or one of its components is missing'"
If you cannot upgrade to SOLIDWORKS 2019 SP2 (which should permanently resolve the issue), you can try this quick workaround:
1. In 'Tools' > 'Add-Ins' clear both the 'Active Add-Ins' and 'Start Up' checkboxes for ALL listed Add-Ins and click on 'OK'.2. Close and restart SOLIDWORKS.3. Start SOLIDWORKS SimulationXpress (or load the SOLIDWORKS Simulation Add-In if you use that instead of SimulationXpress) before doing anything else - avoid loading other Add-Ins until SOLIDWORKS SimulationXpress/SOLIDWORKS Simulation have finished loading.
Additional details about possible workarounds are available in SOLIDWORKS Knowledge Base solution S-018842. You may also find this forum post useful.
