Accidentally opened a project in 4.10 (Was a 4.7 project)

Hi

Opened a 4.7 project in 4.10 by accident, it has now converted it to 4.10, and will not load, and now can not open with any engine under 4.10.

How do I get it to open in 4.7 again?

Hi ,

Do you have a backup copy of the project in question?
Unfortunately projects are not able to be opened in previous builds if they have been altered in a later engine version.

Cheers ,

Ok, so 30 hours of work gone? Just curious?

I understand that backup is my fault.

Are you not able to open the project in 4.10?

anonymous_user_776011b61 · February 17, 2016, 5:07pm

Hi

No, I get this

Have you updated the substance plugin to be compatible with 4.10?

Hi

This is the plug in, not even sure what it is for

If I try, I get this

Are you able to open and work in a clean, blank project in 4.10 or do you get the same errors?

Hi

No, I have start a few fresh projects. 4.10 seem to be fine by itself

Try completely uninstalling the substance plugin, then re-installing. It may be registering your previous substance version which is why you are getting that error message, removing it and re-installing may fix this error.

Hi

There is no Dropdown to remove it, got the same issue with Kite Demo.

You could try to remove the plugin manually in your .uproject file(If you do so, please back ip up before you make changes!). However, if your project uses substance files, it could result in more problems as I don’t know what happens if you forcefully remove the plugin.

Open your .uproject with notepad and remove the following lines:

		{
			"Name": "Substance",
			"Enabled": false,
			"MarketplaceURL": "com.epicgames.launcher://ue/marketplace/offers/2f6439c2f9584f49809d9b13b16c2ba4"
		},

Notice the comma at the closing bracket. Depending on your installed plugins, it might not be there.
