Student licenses should include the toolbox functionality, is this on a school machine or your own personal computer?
First lets locate your toolbox files, these are typically installed in a directory on your C:/ drive. Typically C:/toolboxdata if there's multiple they'll be numbered. Open the folder you should see a folder structure similar to the one below.
Next open the browser folder, you should see something similar to below.
Does yours look the same?
If it doesn't that's the problem and i can help you fix that.
If it does look correct we should try repairing your installation of solidworks, to do this launch your control panel navigate to programs and features ( where you uninstall a program ) right click on solidworks and select change. The installation manager will launch, from here select repair installation. Finish the repair and test again, if this doesn't resolve the issue we'll look at next steps.
it resolved my problem !! Thank you alot !
