Z50 - Error when updating Touchpad driver.

Using a Z50 with Windows 10.

 

My touchpad usually doesn't work. (From what I've read on this forum, that seems to be common.)  I want to update the driver (39lc01af.exe), but I get the error message:

 

"The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more details."

 

I did that. I got this message:

 

Activation context generation failed for "C:\Users\xxxx\Downloads\Lenovo drivers\Touchpad Driver (Elan, Synaptics)\39lc01af.exe".Error in manifest or policy file "C:\Users\xxxx\Downloads\Lenovo drivers\Touchpad Driver (Elan, Synaptics)\39lc01af.exe" on line 0. Invalid Xml syntax.

 

From what I can tell, it's an error in the first line of driver file itself. Is there any way around this?

Hi there, Shawn          -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

Please reinstall the redistributable packages and then check for windows updates.

 

Update us how it goes.

What do you mean by "The redistributable packages"?

I hope you don't mean the driver file I downloaded, because that means you didn't actually read my original post.

A redistributable package (or a "redistributable") is a library of components required to run certain Windows applications developed with Microsoft Visual C++. ... They can also be downloaded from Microsoft's website and installed manually.

 

Update us how it goes.

Re: Z50 - Error when updating Touchpad driver.

You say it can "also" be downloaded and installed manually. Does that mean there's an easier way?

If not: There are at least nine versions of the Visual C++ redistributable package on the Microsoft website. Do I have to reinstall them all?
