Driver download

Hello, I'm Sky64 , I have a VAIO Notebook NW Series with the model number of PCG-7184L . I have installed a software of video editing . After the installation page is done/closed , there's a warning said about the driver has a unknown digital signature that haven't been signed. Then I open my device manager and saw that there's one CD Drive that has one unsigned signature . I deleted the signature and tried again by rebooting my notebook . Although that , it still won't work ! But there's a new warning said that " Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) " . Fearing that this notebook is error , I decided not to do anything anymore ! Please help me , I need this notebook driver to install another softwaree . I didn't use the external CD Drive either and I'm not going to buy one .
