Windows 10: Self Extracting file no longer opens after last update

I'm trying to open a self extracting file to download a firmware update for a camera. Nothing happens when I click open or run as administrator. This same file worked just fine in November when I downloaded it for another camera. After hitting open 10 times or so I can finally get it to open only to get an error message telling me to close all applications and reboot windows. Then I get a WinRarSelf Extracting archive message that says ExtA_update\firmware\fwbin cannot create A update firmware.


I'm about to scream. It seems with every windows update something else doesn't work.

Extracting Zip Files


Are the step-by-step processes identical? That is, the folder extracted from and the folder extracted to belong to the same hierarchical file system structure. If they are, that suggests mildly the Cumulative Update left an electron or two out of place.

 

Extracting Zip Files

Thanks pyramid10 for your contribution, I ensured that the steps taken and the source and destination folders were the same, in the using zip7 as suggested by BunnyJ resolved all issues for me.
I am the first to admit that I am a long long way from understanding the intricacies of computers and if truth be told I am now to old anyway to absorb much information.
Cheers.

 

Trouble extracting Rar files

Is it possible that there are more parts to this .RAR? When files are large, they usually get broken into smaller self-extracting .rar files that use redundancy to make sure the whole file get's unpacked.

I'd imaging UT3 would be pretty darn big. How big is the .rar you're opening?
