Altera/Quartus

jtagserver.exe not starting

(Taken from http://www.alteraforum.com/forum/showthread.php?t=36775)

I have a new solution for those of you who cannot get it to work:

This applies to you if: You have the Altera USB blaster or other programmer drivers installed as expected, and it shows up in device manager under USB without a yellow mark. You have a 64 bit version of Windows You have a 32 bit version of quartus

The symptoms are that a USB blaster (or any other type of programmer) does not show up in the programmer in Quartus II version 12.

The problem is the programmer service (jtagserver.exe) cannot be installed because it is missing tbbmalloc_proxy.dll and tbbmalloc.dll. There is no good reason the jtag server should need tbb - it isn't exactly a performance critical component! This problem occurred during installation of quartus, but no warning was shown.

To fix it, grab the required files from here: http://www.omattos.com/quartus12fix.zip

Extract to C:/altera/12.0/quartus/bin64

Next, install the jtag server as it should have been during installation: Start > search for "command prompt" > right click it and "run as administrator" > type the following commands:

cd C:/altera/12.0/quartus/bin64
jtagserver --install
jtagserver --start

Now all should work as expected!
