I have the same issue. All my other creative cloud apps updated just fine, but Lightroom CC will not update to 2015.8. I receive Error U44M1P7 from the Creative Cloud Application. Installation progresses to 100% and then fails. I tried uninstalling Lightroom CC and it uninstalled fine. It reinstalled fine, but then the update fails again. Following the troubleshooting for Error U44M1P7 just results in Error 49. I tried manually downloading the update form Install Photoshop Lightroom , but that also goes to 100% and then fails, and no error log is generated. Please note that wen extracting the setup.zip file it always gives an error that Assets1_1.zip is corrupt. Regardless of the browser used to download (IE, Chrome, Edge, Firefox) or which Zip extractor is used (Windows, 7-Zip).
Please refer the article "Installation failed" error U44M1P7 with Adobe Creative Cloud or Adobe Creative Suite 6 updates and follow the steps mentioned.
Then,try the direct link Install Photoshop Lightroom
If that does not help, Uninstall Lightroom and install Lightroom 6.0 from http://trials3.adobe.com/AdobeProducts/LTRM/6/win64/Lightroom_6_LS11.exe?PID=2159997 and update it to latest 6.8 from the direct download link above.
I just manually downloaded the 6.7 updater and extracted the setup.zip file with no errors. So there's something wrong with the setup.zip file that is on the download site for the 6.8 updater. It has a CRC error in Assets1_1.zip.
Also already tried all the methods listed above and Lightroom installs just fine, but the 6.8 (CC 2015.8) update will not install and will fail after indicating 100% completion.
I just tested on multiple computers running Windows 10 that setup.zip for 6.8 has a CRC error in Assets1_1.zip.
Same here on both my machines
Similar problem here with LR 6 (not CC): update from 6.5 to 6.8 => errorcode U4M1P7.
Then I downloaded the patch installer for 6.8.
Same error code.
OS is Win7/64.
What can I do?
I did this - didn't work:
- first deinstalled this wrong LR6
- new installation of Lightroom_6_LS11.exe / ok
- AdobePatchInstaller.exe for 6.8
=> error code U44M2P7

Here's what finally worked for me.
First whenever I downloaded the update, whether through the CC App or the manual download, from my work PCs; I would get a corrupted download in the file Assets1_1.zip, and the update would not install. I did this on multiple computers, with multiple OSs and the results were always the same.
Over the weekend I manually downloaded the update from home (Comcast) and that copy was not corrupted. I uploaded the update to my Microsoft Onedrive cloud folder and then downloaded it from work today and it still unzipped just fine. The update then installed without a hitch.
So it seems that whatever server I am being redirected to for the download at work has a corrupt copy of the setup.zip file, while the one I am directed to at home is just fine. Looking back through the forums it seems like this has happened before and Adobe needs to check how they are distributing these updates to make sure people are downloading files without corruption issues.
Suggestions like that will likely not help anyone on Windows until you replace the 6.8 zip file with the CRC error, which "jayparedes" told you about. I checked again just now and it still has the problem.
It's too strange for me and costs too much time.
In the meantime I went back to an image that worked. And stay with 6.5...
This took just half an hour instead of longtime researches.
Thanks for help.
Similar problem here. I have been a LR user since LR3 and never had a problem until the LR6.8 update. My LR will not run after this update. Just want to be on the safe side and skip LR6.8 for now. After this problem has occurred, my solution to restore my system is to reinstall LR6.0 (luckily I still have this file in my hard drive) and then run the LR6.7 update file that I download from Adobe web site. My system is now back to normal.
Adobe. Thank you for wasting hours of my time to install/remove/download/reinstall/remove/download/install/install... LR6.8/6.7/... (via Adobe download manager and via downloaded file) I will stay with LR6.7 until I buy a new camera and lens.
We're tracking this install issue and would like to gather some logs. Could you please follow the instructions here to produce a log so that we can track down where the corrupted file is hosted? Log Collector Tool
Please send them to me at rios [at] adobe [dot] com with the subject line "Lightroom 2015.8/6.8 Error U44M1P7: CRC Assets1_1.zip".
Melissa, thanks for acknowledging that there is problem with the Installer, a step in the right direction. Given that this issue has existed since LR 6 was first released it's disappointing that this admission has taken so long.
Can I suggest that the next version of LR is first issued with a Release Candidate for users to try out, a sensible procedure that was used with previous versions.
Any news or a schedulle for that fix?
I still can't update.
I only received one user's logs 7 hours ago. We'll need more logs from other users affected to investigate. I'll find some other way for you to install though.
Please send me your logs!

I solved the problem asking for my friends to use the direct download (send the link to them). One of them also got the corrupted file... but two got a working file (each one of them tried to decompress the file to see if it was OK). They sent me the .zip through WeTransfer and I could update my Lightroom.
People with problems can try that too, using other computers, on different networks or ISP to get a working file.
Worked for me.
Anyway, thanks for all your attention!
Same problem here, no workaround work.
Logs send by email as requested.
Thanks in advance.

will you mind sharing the onedrive or dropbox link to download the correct copy of the installtion file? same CRC error here from Official download link.
Thanks for that. This update file works correct.
Thank you so much for sharing that with other users on the forums. That's extremely kind of you.
Thank you for the logs!
Would you also mind sharing logs with me?
Thanks to everyone here for coming back to the conversation. I'm still talking with two different teams about this. In terms of this happening in the future, there are plans to change/fix this process so hopefully, this will prevent any of these problems from occurring in the future.
Lightroom CC2015.8 Update on Windows 10. Same problem here, I did everything, I've tried to install it both ways, with creative cloud and with a corrupted setup.zip and there's no solution.
I'm sending my log, please check that setup.zip on server, the folder Assets1_1 is corrupted.
Well, the Dropboxed setup file fixed it, many thanks.
All other direct 6.8 downloads were corrupt and would not install, hence the missing files in the error logs when using the Creative Cloud app to update.
So all my uninstalling, reinstalling, cleaning and retrying for a full day was for nothing, as Adobe simply has sent out corrupted files.
By the way, why does the official Adobe help page link to a commercial 3rd party for the updated files?
It links to a site which hides its links behind some ad/affiliate server (resulting in 404's for me) which makes it very illegitimate.
jayparedes I fully agree Adobe needs to do something with the distribution of their files. I wasted the whole afternoon trying to fix this. Now I will have to stay working until midnight to catch up... Very disappointing on Adobe. Thanks for pointing out the problem.
axmelissarios1 Hello Melissa, you have to move the "correct answer" flag from your post to RaphaBonelli dropbox link since that's the actual solution (and jayparedes was the one that come with the right diagnosis). I was confused for your flag as the correct answer and almost didn't keep reading because until that point it was looking as no answer. I know other users scanning thru the post won't be able to see the link to the dropbox. Please fix, thanks!
Thank you, thank you, thank you RaphaBonelli! I just spent 2 1/2 days going round and round with tech support dealing with this, even though I told them from the beginning the assets1_1.zip was corrupted. Finally when he said we think it is a corrupt user account I said stop! What makes it even more frustrating is that the answer has been right here on their website for a month! Thanks again.
Still same problem and no solutions in sight. While trying to update from 6.7, not only update failed by myLR wnet back. to 6.0 and I'm stuck with it. Help!!!!!!
I am a CC full subscription user-have been for 3 years. Windows user.
I had CC with LR(6.8), PS, DW, Acrobat, Media Encoder working without problem on a Win10 Pro desktop and Win10 Pro Laptop. All versions were current (LR@6.8). No problem until:
I bought a new W10 desktop computer and deactivated the Laptop so I had an open CC install.
So I did the same procedure I've done many times before. Installed the CC program on the new computrer and then downloaded my apps. I figured that all apps would install with the most current version, I mean who'd expect an old version with a fresh install since its a web download. Seemed true for all but LR which installed as 6.3 (huh!, I installed late Feb 2017). I then got the CC notice for LR "update available."
Same problem as reported in this thread "error u44m1p7." I tried the solutions recommended by Adobe for this error:
None of them worked and I got the unzip CRC error when I downloaded the update manually.
Two call two tech support with two remote sessions to my computer. Each lasted about 1 hour and lots of changes to permission on Adobe folders, downloads, reinstall of LR, all while I watched my desktop changing under remote control. Trusting person I am (maybe I shouldn't be LOL).
Each time no solution. and each time the tech said he will escalate the problem and Adobe will call back in 1-2 hrs 1st session (never called) or 10-20 minutes 2nd session (never called).
Really not happy so I went to the LR Adobe forum (should have done this first but never had any problem with CC or LR ever!).
The solution that worked was to use the dropbox setup file provided by RaphaBonelli (which unzips with no CRC errors):
The date this worked for me is March 1, 2017. Yep, March 1, 2017 and the problem is still occurring when you update LR via the CC program or you follow the Adobe advice and try their 4 solution (helpx link) or call tech support.
Live and learn but what a gigantic waste of my time. I hope this saves someone else some time.
