Do you have experience with this problem or have an idea to solve the problem listed below?

My team is having a problem opening a 4.2.1 project with the 4.3 editor as it produces the following error by either selecting OPEN A COPY or CONVERT IN-PLACE from the convert project dialog:

Project files could not be generated. Log output:
Running C:/Program Files/Unreal Engine/4.3/Engine/Binaries/DotNET/UnrealBuildTool.exe -projectfiles -project=“D:/Users/User/Documents/Unreal Projects/Test/Test.uproject” -game -rocket -progress
Discovering modules, targets and source code for game…
UnrealBuildTool Exception: ERROR: Expecting at least one ProjectTarget to be associated with project ‘D:\Users\User\Documents\Unreal Projects\Test\Intermediate\ProjectFiles\Test.vcxproj’ in the TargetProjects list

If we try to SKIP CONVERSION, we will get an error that Project modules are missing or out of date, then the engine is out of date for the project. Trying to open will cause UE4 editor to crash.

We are using Perforce, UE4 Editor 4.2.1(no more), and UE4 Editor 4.3(Now).

Hi Bergwen,

You must convert your project to 4.3 if you want to work on it in the 4.3 version of the editor. The safest way to do this is to Convert by Creating a Copy. This will make sure that your 4.2.1 version stays safe just in case something doesn’t convert correctly.

Thanks, TJ

TJ,

Thank you for the reply, I tried downloading a fresh 4.2.1 version from our depot and I tried to convert by creating a copy and this did not solve our problem. Thank you for the suggestion though.

Kind Regards,
Bergwen

Are you compiling the engine from source or using a binary version downloaded from the launcher?

TJ,

I have linked the documented steps that we have taken to open the project with 4.3 editor. I hope this helps you understand our problem.

I still haven’t been able to reproduce this, so I’m going to escalate your issue.

I see from your steps that your project is a code project, correct?

Could you also post your dxdiag, LOG, and DMP files. The following link contains info on were to find this.

TJ Ballard,

The information that you have requested is not available but the dxdiag information as I reinstalled UE4 and wiped the folder that contained any remains thereafter. I reinstalled the UE4 engine and my team deleted the binaries from the project and we were able to upgrade the 4.2.1 project to use it in 4.3.
