System Update does not start—what to do?

Hi,
Here are my machine details.
T60p ThinkPad, model 2623DDU and operating system is Windows 7.
System Update 4.03, the latest version has been installed on my system.
Anyway, I get an error shown in the screenshot as I try to start the application.

Application has generated an exception that could not be handled.
Process id=0x9fc (2556), Thread id=0x1a04 (6660).
Click OK to terminate the application. Click CANCEL to debug the application.
I completed the setup with ignoring the similar error.
Please give me your suggestions to fix this error.
Thanks.
