I am running an academic license of SW2015 on a Windows 7 64 bit machine. Windows shuts down SW every time I try to use Evaluate tool Measure to check the distance between two parallel surfaces. But that is not my primary concern. I just discovered that I an locked out of service pack downloads! I realize my academic license does not pay the bills DS but gee whizz? Please tell me I am missing something.
Sorry to inform you that you are not "missing something". Service Packs are not accessible for student editions.
Pitiful isn't it.
Regarding the Measure tool, I don't know what could cause that. However all sorts of seemingly unrelated problems can be caused by using a non-approved graphics card and driver. Run the SolidWorks Rx > Diagnostics tool to check.
