I tried to do the following based on your suggestion, but i still get the same error.
Goto My Computer, Click Properties, In the Hardware tab, click Driver Signing button.
I have tried setting the option to all three settings : Ignore, Block and Warn.
But I get the same error when using any of the three options.
I am trying the install the “WinCDEmu-3.3-signed.exe”
I am on WinXP SP3
