not able to connect USB to Serial Adapter

Hi Everyone, I am using uVision3 for Silicon Lab C8051F020 Microcontroller. As My laptop doesn't have Serial port, I am using an USB to Serial Adapter.
When I am trying to connect/debug, it is showing
"***Error: C:\Keil\C51\Bin\SiC8051F.Dll" invalid debug Dll.

Also, when I am opening uVision3 Debug settings in "Configure Flash Tools" menu, I am not able to select the "USB Debug adapter" option.

Can anyone please let me know, how to fix this?

Thanks and Regards
Rajesh

    I have had the same problems in the past.
    1. Make sure that you have the latest drivers from SiLabs. I don't have the drivers on this computer so I can't give you any help on the latest driver version.
    2. Many Laptops will not drive a USB/Serial converter attached to the SiLabs C2 box. I had to go to a self powered USB hub which fixed 90% of my problems.
    3. Under the Keil Options -> Debug tab, ensure that you have the TCYG.DLL with options -pCYGF020 loaded.
