“Path may not contain the following characters: &”

I’m getting this error when I want to convert my 4.4.3 project to 4.5.1.

As far as I know I’ve never used the “&” symbol.

Any help would be great.

Thanks!

Hey -

Do you still have this problem if you sign out of the launcher, close and then sign back in? If you create a new 4.4.3 project and convert it to 4.5.1 do you get the same message? If you could give us any more information or a screenshot of the error message it will help in determining what the cause is.

Cheers

Hey ,

Thanks for your quick reply!
Unfortunately I’m not able to test these things right now since the problems occur at my work and due to the weekend I’m at home.
I will try the things you suggested as soon as I’m back in the office. If problems persist or if the solution is in your suggestions I’ll come back to you with the details.

Thanks again.

Hey ,

So I have tested your possible solutions but without succes…

If I create a new project in 4.4.3 and convert that to 4.5.1 no problem.
If I convert a 4.4 marketplace project to 4.5.1 no problem.
Signing out of the launcher restarting the does not help.

I think I used an invalid character somewhere in my project.
I’ve attached an screenshot of the error.

Thanks for looking into this. Much appreciated.

Hey -

Just for clarification, when you are converting your project are you choosing the option for “Open a Copy” or “Convert in Place”?

Hey ,

I’ve actually tried both without succes.

Could you find the exact path that the original project is saved in and post the file path here? Also, another method of converting the project would be to navigate to the project’s save location and right click the .uproject file. Select the option to “Switch Unreal Engine version” and select 4.5 in the window that opens. You may want to make a backup copy of the project before hand to be safe.

Sure here it is I made another Screenshot to be sure.
I must say It is a network path that I’m using could that be a problem?

Hey -

The folder named “Unreal Engine R&D” is being picked up when you convert the project from 4.4 to 4.5. If you rename that folder by removing the “&” you should be able to convert without an issue.
