Problem

What steps did you take in CKAN?
I selected about 60 mods from the compatible list and then selected apply, then CKAN proceeds to Download the mods.

What did you expect to happen?
Clean download and install of selected mods.

What happened instead?
Threw an Unhandled Exception when finished downloading.

Looks like a problem with one of the ZIP files. Are you able to install these mods individually?

[ErrorSys]

Unfortunately, I am not. I have tried many times however im not able to get mods to work together, and I resorted to using CKAN. How would I go about finding which zip file is causing the issue? I might be able to fix that.

[HebaruSan]

Oh, I meant to try installing a smaller selection of mods, but still using CKAN, until you find one that causes this error by itself. If we knew which mod it was, we could look at the file to see what's wrong.

[ErrorSys]

Found which one was causing the problem:

Installed each of my selected mods and that one was the only one that caused the Unhandled Exception.

[HebaruSan]

Nice! I get many errors like this trying to unzip that file manually in Windows:

Possibly because of the quotes in the filename? There's also a __MACOSX folder in that ZIP, so I think we can guess how this happened.

I've submitted two issues to that mod's repo, linked above; hopefully he'll fix it.

[ErrorSys]

Anyways, I don't know if there are other mods that have this problem. I would check all of them but I just don't have that kind of time or patients to do so. I hope I have helped in resolving this issue.

@ErrorSys Fixed in the new version of my mod. Sorry for any inconvenience caused.

Confirmed that the latest version is indexed and installable on Windows. Thanks for the fix!
