I keep getting this error when I try to export my mod package. Any solutions?
Mod Constructor - "Cannot create a file when that file already exists."
For me, I had downloaded the wrong version of Python. I downloaded the most recent version which is version 3.8.2 as opposed to the recommended 3.7.0. After realising this, I Uninstalled and installed the current version (3.7.0). I tried to export my package again as was met with the error you mention above: 'Cannot Create File When File Already Exists'.
1) Firstly, ensure that you have downloaded the correct version of Python (3.7.0)!!! If you have not got or downloaded this version then please Remove/Uninstall any other version of Python BEFORE you download the correct version.
2) Open the file where you have downloaded/exported 'Mod Constructor' to. Then click Mods>'YourModTile'>Python. Delete the files in this folder that have the name of the mod you want to export. There should be a Python File and a Compiled Python File (these are what you want to delete). Then Click the _pycache_ folder and delete all the files here. This is where I found 2 compiled Python Files (one for version 3.7.0 and one for 3.8.1), so I assume that Mod Constructor was not able to save the file due to a conflict of version and thus produced the '...File Already Exists' error.
3) Reboot Mod Constructor and try to save again. Hopefully, you can now save as I have been able to!
