Hello, I am making use of the Windows 7 Ultimate 32bit on my Toshiba Satellite L45-S7409. Some of the function keys are not working programming. Then I come to know that the TVAP installation will solve the problem. So, I simply download it and then try to install it. But, I am not able to install it. I am getting the error message that the Setup TVAP error 0x8146045B. If you are having any solution on this, then please help me. Thank you in advance.
