While debugging with the hardware connected ,the below error pops up and debugging halts... Any solution available for this issue? Downloading ELF file failed "

Thanks for the response.😊

Actually in my installation directory nios2-gdb-server.exe file went missing after i try to debug application in my PC. Now it shows new error " .gdbinit: No such file or directory." Again if i try to build my application program it will not compile properly and elf wont be generated showing some new errors in application.

The same hardware set including usb blaster is working in other PC with same version of Quartus software 18.0 and same application software.

I tried reinstalling the quartus twice but it did not help.
