Control Panel installation error ("Please make sure Quartus is installed")

Hello,

I am trying to install the DE2-115 board under Windows 7 professional 32 bits.

While trying to run the Control Panel I get the error

"Please make sure Quartus is installed".

Quartus II is installed, and works very well (I have created and run on the board

2 small examples).

The USB blaster seems to function correctly, as reported by both Windows

and Quartus II (using Tools\Programming correctly lists the device).

The versions of both Quartus and Control Panel are those available for

download at Terasic (I also tried the DVD versions that came with the board,

same problem).

Following advice found on this forum, I have copied the jtag_client.dll and

dinkum_alt.dll to c:\Windows\System32 folder. Since then, I no longer

have the "Cannot load jtag_client.dll" error I had in the beginning.

Also following advice found on the forum, I have added the path to

nios2eds (...\nios2eds\bin and ...\nios2eds\bin\cygpath) to the system path.

(I did not reboot the computer since, but I don't think I should).

Still, I get that error while executing cotrol panel.

Thanks in advance for your help,
