I have scoured the web looking for someone who can explain this, and there is nothing current. I get this error when I use either the Office 365 Installer or Create an ADR option.

Beyond frustrated. I only went to this method after our Office 365 Application, which had been working just fine, all of a sudden stopped and giving some wild error with a – sign in front of the 2nd number.

Any news on this or further helpful info?

Hi ,
Any idea on i640.c2rx file in windows

Probably something of a one-off, but just in case this drives anyone else up a wall…
I was getting error = 87 – could not find anything referring to that anywhere. Patchdownloader log in my user profile folder (appdata\local\temp) wasn’t even much help – generic filesystem error 0x80070057.
Ultimate solution was tied to my username. We had been using admin IDs with a ^ in the username to identify our admin IDs. I’d removed that from my ID several months ago, but it was still in my profile folder name.
Deleted my profile and built a new one without the ^ in it and the download completed without any issues.
Hope this helps someone else. 🙂

I had this exact issue with SCCM 2107 in February 2022. I tried every workaround found on the web: removed the KB, opened Firewall ports, added permissions to the packages folder. But what did the trick was saving the files on a different volume than the default one used for all packages. I just saved it on an empty volume attached to the server and it worked perfectly, the error was gone and I could download the entire Office365 suite.

Hi Onfrej ,

I confirmed your solution under 2103 too .

Regards

I am not sure if that should be considered as fix.
