A problem with Quartus Programmer v10.0

[Altera_Forum]

Anybody understand this error code??? 

 Internal Error: Sub-system: PGMWQ, File: /quartus/pgm/pgmwq/pgmwq_device_dlg.cpp, Line: 343 Invalid Initial family Stack Trace: 0x5aaea: pgmwq_select_hardware_and_close + 0x8baa (pgm_pgmwq) 0x635d0: pgmwq_select_hardware_and_close + 0x11690 (pgm_pgmwq) 0x276c35: QWindowsXPStyle::styleHint + 0x2d5 (QtGui4)  End-trace   I was trying to change the frequency properties of an EEPROM device, but this message came up and the program stopped.

usually there isn't enough information in the trace to gather any useful information. though yours does say Invalid Initial family 

 can you provide steps to reproduce this and/or file an SR?

I Dont know a lot about the device itself only that its An EEPROM(EP20K1000EFC672).

ok this is as i was expecting. APEX 20K is a bit older of a family. i'm not sure which versions of the programmer supported it. try taking a look at the device support in older release notes to find APEX 20K:

it still shouldn't have an Internal Error, so file an SR if you can
