I'm having the same problem on my laptop. My desktop loads fine, but the laptop gives me error U44M1|200.
Laptop currently has LR 2015.3 installed. Running Win8, Intel Core I7, 8Gig RAM. Old LR works fine.
I get the same error trying to update Bridge and Photoshop.
Did you try the solution in reply #1?
I just finished downloading LR using that link. It worked.
Now I need a similar solution for Photoshop and Bridge.
Please refer the below update link for Photoshop & Bridge
Just tried those links and got "You don't have permission to access..." on both of them
On second try I was able to download the files. Photoshop 2015.1.2 is now installed. It does report a graphics card problem, but it seems to do everything I tried out on it.
Was finally able to get my computer back online today. My current version of Lightroom is 2015.3 and Camera Raw 9.3 according to the about window.
The link you provided says (after I download it completely) Twice!:
Updates could not be applied
Adobe Application Manager may be damaged. Download and install a new copy of Adobe Application Manager.
If problems persist please contact Customer Service for further assistance.
When I try that link it also shows UPDATE FAILED.
No ideas, still can't get past any LR updates at all, Bridge showed I needed an update, it worked fine.
Still getting the same LR update error after a fail at 54%.
