jtag_atlantic.dll missing

Hi all,

I am using Quartus and Nios EDS 10sp1 on winddows 7 64bit. I cannot run nios2-terminal command, it gives an error like this:

"The program can't start because jtag_atlantic.dll is missing from your computer. Try reinstall the program to fix this problem."

After trying to copy the jtag_atlantic.dll in folder \altera\10.0sp1\quartus\bin64 and E:\altera\10.0sp1\quartus\bin to windows\system32. It gives another error like this:

"The application was unable to start correctly (0x000007b). Click OK to close the application"

can anyone help me to fix it?

PS. Today I use modelsim to simulate NIOS II, and I issue a command jtag_uart_drive to display an interactive console. The result is no window appear and i discover the problem, I cannot launch the nios-terminal!

Thank in advance.
