It's a backup from other computer. It was opening earlier but I have to clean out everything and now trying to restore it and this error comes up.

Any leads would be appreciated.

Thanks

Answer 1

Hm, the file could be corrupt?

I do not understand

It was opening earlier but I have to clean out everything

- are you saying you changed the zolca file?

Thank you for your response.

It seems like file is corrupted, but I have not changed the extension type. It is still zolca file.
I don't understand how it can be corrupted.

Answer 2

A zolca file is a plain zip file. To check if it is corrupted you can try to open it as a zip file (e.g. using 7zip). You can also manually extract the zolca archive in the `~/openLCA-1.4-data/databases/<database name>` folder and add the corresponding entry in the  `~/openLCA-1.4-data/databases.json` file (just check how it is done for the other databases in that folder; but it is good idea to backup these files first; also, do this when openLCA is closed).
