0x800700c1 is ERROR_BAD_EXE_FORMAT. It likely means that Google Update's COM registration is somehow broken. Please open up a cmd prompt then:

> cd %LOCALAPPDATA%\Google\Update
> dir

You'll see one directory in there that is Google Update's version (e.g., "1.3.30.0" or somesuch). Change into that directory:

> cd 1.3.30.0  <-- use the actual number you find

Then run the following command to force Google Update to re-register itself:

> GoogleUpdate.exe /regserver

Now restart Chrome and try chrome://help again.

If this doesn't help, please reply with the actual version # you find in the Google\Update directory.

+1 to what Greg said. GoogleUpdate.exe /regserver should be the first step.

In the past, we have seen this when the 64-bit proxy/stub for the GoogleUpdate COM server has not been registered. psmachine_64.dll or psuser_64.dll respectively for ProgramFiles or User installation respectively. 

Hi. Have you been able to get Chrome updating again? If all else fails, you can try reinstalling canary from https://www.google.com/chrome/browser/canary.html?platform=win64.
