Wrye Bash error code: "Extraction failed: 7z.exe return value:7"

[elcameron]

I'm restructuring this post to be more of an explanation than a question, because there is technically no fix for the problem.

First, please read the original post that explains the problem better than I could here: https://www.reddit.com/r/skyrimmods/comments/7mg9q5/wyre_bash_extraction_error_7_help/

I am attempting to recreate these 2 builds which are supposed to work stably with each other in Oblivion: https://www.nexusmods.com/oblivion/mods/47591

https://www.nexusmods.com/oblivion/mods/48448

I am following this video guide to walk me through the first build here: https://www.nexusmods.com/oblivion/articles/44213/?

I have received help from Bevilex, the OP of the Reddit post I linked, OutdatedTV, Sinitar & Sinitar's Discord, and a little bit here on the nexus forums. There is no fix for being unable to install mods in the Wrye Bash installer tab with this error code:

Extraction failed:
7z.exe return value: 7

I attempted everything, and I mean everything I know of and those listed above suggested, such as:

bash.ini command line edits

fresh installations of oblivion, all of the mod programs from the guide, and even 7zip/notepad++

using different web browsers, storage drives, and folders

repacking the archives

switching between .zip and .7z

running Wrye Bash as administrator

verifying file integrity, making sure no parts involved were "corrupt"

and more

If you receive the above error message, you will have to use projects instead of archives. To do so, right click > 7zip > Extract to "...".

The folder created is a "project" that you can drag into the installers tab and use in almost the same way you use archives. The main difference is that projects are not compressed and you can manipulate files/folders more easily with a project than you could with an archive. As for issues with projects that do not arise with archives, I do not know of any but I'm sure they exist somewhere.

I hope this helps anybody who runs into the same problem, and if anybody ever does come across a fix please let me know.

I'm not asking for this post to be pinned, but if a mod could add a link to this post in one of the pinned posts on this forum I think it would be beneficial to anybody in the community that runs into this.

Greets,

 

I just had this 7z error. Never had it before putting Oblivion together with Wrye Bash.

 

I had just re-installed Windows 7. However I was trying out a Ram Disc of 1 gb for Temp memory.

 

Turns out I was running out of memory when I got to Qarl's Texture Pack III Redimized.

 

Went back to "%USERPROFILE%\AppData\Local\Temp" for memory on Disk.

 

Worked just fine.

 

Never got a low or out of memory error.

 

Just the 7z error.

 

Hope this helps!

 

To Your Great Health!
