proj_create: no database context specified

I’m seeing the exact same issue as previously reported in [Offline Installer 5.1 and georeferencing [Content removed] Do you have any updates on how to get the GeoReferencing plugin working with the offline installer?

Hi,

Sorry to hear this. It reminds me that I never heard back from the Offline Installer team about this issue.

This is really weird because all files were correctly included in this installer.

The workaround should still be valid, having the plugin copied locally in your project folder.

I’ll do further investigations and keep you posted.

Hi,

I’m a little bit puzzled because I tried to reproduce your issue this morning but wasn’t able to. Everything was running fine on my end.

I did not have the offline version installed, so I downloaded it from the devportal (5.5.4 [Win] - Mar 11, 2025), and installed it.

I created a new project from the UI, using the Simulation/Blank template.

I added a UMG Status bar widget to the main viewport and tried different packaging modes. (dev, Shipping).

In all cases, I was able to have the display of the coordinates and their correct conversion, confirming that proj.db was correctly loaded. (The log file was fine too).

To be really sure, I uninstalled the UE 5.5 Launcher version I had on my computer, rebooted, cleaned up my test project, and the same tests gave the same success.

I don’t really understand what’s happening there. I’m wondering if anything special is happening with your specific project, or if it could be related to the installed VS toolchain.

  • Can you try to do the same with the Simulation/Blank template?
  • Is it possible to have a simple repro project that fails on your system?
  • If not possible, can you share a log file of the build/package process and from the runtime execution?

FYI, I’m using this toolchain when building:

Using Visual Studio 2022 14.38.33141 toolchain (C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130) and Windows 10.0.22621.0 SDK (C:\Program Files (x86)\Windows Kits\10).

We upgraded the version of the PROJ library between UE5.1 and UE5.5, which could explain why it works on my computer (I was indeed able to reproduce the problem with 5.1, but not now).

But it doesn’t explain why it fails on your system.

We ended up getting this working by using the Launcher version to unblock this and we’ll probably switch to source builds as the next step. We actually saw a couple other errors that were exclusive to the offline installer as well. It’ss no longer a pressing issue for us because we can work around it, but let me know if it would be helpful and I can try to provide a minimal project to reproduce. Note I’m about to leave for vacation, so this would have to wait until June.

Hi,

Yes, if you have a simple repro project, it would help investigate. I understand the workaround helps, but I definitely want to understand why it failed on your system and not on ours.

But no hurry, have a good vacation, and come back to us when you can!
