chrome wont update

pls do zip that folder. I will give it a go!!

Here you go. Thankfully, zipped up it's just under the limit for ZIP files.

thanks Deckard. Will update when done with my findings

Great! Glad to hear it.
As I said, if it happens again I will dig deeper, but I suspect "GoogleUpdate.exe" is dependent on one or more of the DLL's in that "1.3.33.5" folder. You'll notice there are a bunch of GoogleUpdate* EXE and MSI files in there as well, but I don't know if any are called during the update process. Either way, I'll report back here if the issue resurfaces.

Ripper and thanks again Deckard. I have been trying to find a fix for years and no one has been able to help including the chrome forums so you are a genious for cracking it.

You're welcome and thanks for the kind words, although I wouldn't go so far as "genius" - it's usually just knowing enough to get myself into trouble

haha. Well well done in any case. I have tried so many uninstall re installs etc. I was almost going to reformat but I have so many programs with custom settings that it would have been a nightmare

Successfully updated Chrome this morning via Help > About on one of the machines that was giving me problems. Now on "Version 60.0.3112.101 (Official Build) (64-bit)".

I can confirm same here. Whoohoo!!!!
SUCCESS!
