bibisco version 1.X FAQ: Frequently Asked Question
This error happens when you move or delete the directory in which bibisco stores the projects outside the application.
Download again bibisco 1.X version from here, unzip it and start again (attention!! Don't download bibisco 2.X version from official web site, because starting with version 2.0, bibisco is based on a completely different technology (node.js) compared to version 1.0 (java), so the projects realized with version 1 of bibisco are not compatible with version 2).
When start again choose the moved directory as the directory in which bibisco stores the projects.
To launch bibisco on Mac follow this instructions:
For El Capitan and previous versions, on System Preferences -> Security and Privacy, you must have "Allow apps downloaded from" set to "Anywhere.".
For Sierra you have to follow these instructions: http://osxdaily.com/2016/09/27/allow-apps-from-anywhere-macos-gatekeeper/
The most common reason for this message seems to be unzipping the bibisco.zip file wrongly. Therefore please unzip the zipped bibisco again with a good unzip tool (like 7-zip, http://www.7-zip.org/).
Also make sure that the path to the unzipped bibisco does not get very long. There are cases where bibisco was unzipped into a deeply nested directory structure and that led to the same error message.
If that still doesn't work, you may try launching bibisco.exe with administrative rights. That should not really be necessary, but maybe your access rights are somehow broken after the re-installation of Windows.
