Step 2: You should be now in C:\Windows\system32>. On the command prompt type "cd.." and press enter (repeat it once again). Now you should be on the root C:\>. Just type "cd " + the path to the ActiveX (example: "C:\sipsdk\") and press enter. Note: "cd" is a MS DOS command and used to switch directories.
