Is it actually installed? That panel needs Quartus programmer, to upload fpga image.
Yes, I got Quartus ver 10.1 at C:\Users\pc\altera\10.1\quartus\bin\quartus.exe
I'd offer You to update it to 11.1sp2 and install it to default directory: C:\Altera\...
Ok, so the Control Panel actually installes a program on my device (and erases the program I alreaddy have + EEPROM?)
I am not sure, but probably it uploads a new fpga binary to the fpga itself. But yes, You can expect it to delete some memory contents of other devices.
