I registered for the SOLIDWORKS Design Standard for Students license from the official website and received a single serial number. When I downloaded and ran the SOLIDWORKS 2026 SP2.1 Installation Manager, the serial number entry screen showed multiple fields for add-on products (SolidWorks Composer, SW Electrical, SW Simulation, etc.) that were pre-filled with codes.

When I entered my student serial number in the top field and tried to proceed, I received a license server error (2345@...) for the pre-filled codes. When I cleared all the pre-filled fields and left them blank, the installer blocks progress with the error: "Your SOLIDWORKS Composer serial number is incomplete — most serial numbers have 24 characters."

I cannot get past the serial number screen at all. I was only provided one serial number for the core SolidWorks product and was not given codes for Composer, Electrical, or any other add-ons. There is no way to skip or deselect these products from the serial number screen.  

And i am getting server issue like 2345@..... error etc please advice
