Code 39 driver error

Featured Replies

Posted

Hallo, 

Modified driver sources little bit and compiled without any errors but when loaded the driver got this error - 39 "Object name not found". The platform is windows 10 64bit. The driver worked ok before the modification. Not receiving any debug information also. Please help how to debug this error and what may caused it?

Do you have signed / tested the driver with WHQL / HCK tests?

During development you have to set Windows to test mode so that signature is not checked.
