[Bug]: Error during a fresh installation of ZenlessZoneZero #907
Description
Affected Version
1.84.6 Preview
Bug Behavior
When I disabled Sophon mode (as it is extremely slow in my region) and selected an empty directory for a fresh installation, the following error appeared after all the compressed files had been downloaded, preventing the installation from completing:
System.IndexOutOfRangeException: Cannot find an offset of the Central Directory

Expected Behavior
In theory, it should extract all the files and generate a usable Config.ini file.
Steps to reproduce
- Disable Sophon download mode
- Choose a blank folder to install game
- Download all archives
- After verified all the archives, the error popups.

This should be to be expected as ZZZ stopped serving zip download as of 3.1.0 update. 3.2.0 update is not available in the old zip API so the update fails. This should've been fallback to Sophon as it is other games but alas that mechanism should get fixed.
As of your slowness in Sophon install, can you check how many threads you have in the download ? You could lower or bump the numbers to fit how your internet behaves. Some ISPs like more connection but other don't. Try to fiddle with it and see if it would help!

my bad, i did not scroll down long enough to see that the zip is available LMAO
something something download manually the zip and put the file next to zenlesszonezero.exe and collapse should pick the file up given you also disabled sophon in settings

It won't, as no valid config.ini is generated. Collapse will only download the archives again even I can already launch the game and complete the in-game file check.

It won't help because my region has a very poor connection to CNREL's CDN. Using Sophon mode will waste lots of time on connecting rather than tranferring.
