I am thinking it is something with the SQL Server Express. Do I have the wrong version? I'm running SolidWorks Electrical 2016.
Yes...the SQL server Express is the issue.
Please check the name and the instance.
Try creating a new instance of the SQL server database.
Is it a network installation being used by multiple users?
When you install a new instance of SQL Server, SOLIDWORKS installation provides a free version of Microsoft SQL Server Express. This version is limited to 1 CPU, 1 GB of memory, and 10 GB of data. The memory and CPU limitations are sufficient to support 5 concurrent users.
If you install SQL Server Express Edition, ensure that the server software and hardware meet the requirements listedhttp://solidworks.com/System_Requirements.
However, if there are more 6 or more concurrent users on the same server, you should purchase and install a full version of SQL Server, and use the workflow described for installing SOLIDWORKS Electrical with an existing instance of SQL Server
No, it is only a single user.
We have 2 single user installations that have the same issue. I only got the issue with 2016 SP3 but was ok with SP1 and SP2.
Recently I have reformatted my machine and reinstalled everything and the issue still exists. Manually starting the server under the services resolves the issue till the computer restarts again.
I have found I can decrease the occurrance if I changes the service properites to continually restart on error and have an automatic (delayed) startup.
Ultimately this seems to be one of the many bugs found in SP3 which worked fine in previous software versions.
