  • Hello, recently I was working on a construct 3 project and I saved it in the evening and in the morning I got this message saying : "Failed to open project. Check it is a valid Construct 3 single-file (.c3p) project" I have read other peoples similar problems and I have extracted from a zip file and clicked on F12 next to the message but I don't seem to know what to so next.

    I Have saved this file on drive and it is the v.7 of my project and v.6 and v.5 also do not work but v.4 does.

    Does someone know a way to resolve this?

    Thank you

  • Can you show me what’s inside the Layout folder?

  • I don't have enough room for one screen shot so this is them all

    Thank you very much

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads

  • Looks like the layout name starts with a space - " Playership Start Scren Layout".

    Follow these instructions to fix it:

    construct.net/en/tutorials/fix-open-project-errors-due-3139

  • To maintain consistency and avoid potential issues, it's advisable to use names like `credit_layout_start` or `CreditLayoutStart` instead of including spaces in layout names, variables, objects and etc.

  • I unfortunately have a problem: each version which has " Playership Start screen Layout" is also doesn't open.

  • Open project.c3proj in Notepad, check which version it was saved with. For example:

    "savedWithRelease": 36802

    This means r268.02

    Open the project in that version. Update layout name, save, then try to open with the new release.

  • how should I convert the SavedWithRelease code into a v. 7of my game

  • And also, I cannot find the words in the notepad : "SavedWithRelease when I cick Ctrl F and search for it.

  • Should I edit the space error directly from the notepads code?

  • To open a Construct project in an older version, first, change the file extension from .c3p to .zip. Then, extract the contents.

    Next, open the project.c3proj file in a text editor and find the line with "savedwithrelease": XYZ. Change the XYZ to an older release of Construct where it can be successfully opened.

    Save your changes, compress the files back into a .zip, and rename it to .c3p. Now, try opening the modified .c3p file in the older version of Construct.

  • Only in your case you shouldn't change the release version in project.c3proj

    You need to check SavedWithRelease and open the project in that version.

  • Well, open the project in version 388.2, remove the extra space from layout name and save.

    editor.construct.net/r388-2

  • Ok I did it, so do I now go and reload construct 3 to its current version and open the project and it should hopefully open?

    Should I also edit all the layout names to not have any spaces and have _ instead like Akabaru48 told me to?
