The .7z file you’ve downloaded is an archive, just like a .zip or .rar file. You need to unpack it to find the installer. 

Thank you @TwentyStudios,

we obtained an extraction tool from here: https://www.7-zip.org/download.html

@Aximmetry are there any install notes or minimum specs?

We tried $$$UnrealEngine from the expanded archive obtained from https://my.aximmetry.com/User/MyDownloads

It kicked up an error to say that the .net desktop runtime 3.1.31 was not installed. (We'd already tried this from the advice on an older post and installed it independently from here: https://dotnet.microsoft.com/en-us/download/dotnet/3.1).

Uninstalling it from our test machine enabled us to run $$$UnrealEngine without error until we saw a collection of missing .dll warnings towards the end of the install process:

Unreal 5.0 install completed after we ignored the errors (x4 in total). We've been able to launch Unreal 5.0 and create a new project.

@Aximmetry What are we expecting to face down the road with these missing .dll's?
Errors in cooking for Aximmetry? Live Link errors between Aximmetry and Unreal?
Can they be installed separately?
Is there a minimum machine / OS / Video Card spec we should adhere to for this latest build of Aximmetry / Unreal 5.0 for Aximmetry?
Are you technically still in beta with this version?

NOTE: Windows is not our preferred platform, we are camera operators and enthusiastic troubelshooters, our experience detailed in this post maybe unique to us and our choice of hardware. This post should be treated as a a reference article specific to our particular circumstance. Aximmetry is likely to be already addressing the notes and questions raised in the query elsewhere in their general release and update cycle.

@NYShine: it doesn’t seem you’ve actually installed the correct Desktop 3.1.32 after all. Did you try running the UEPrereqSetup_x64 before inning the installer? 

@TwentyStudios, thank you again for keeping track of my ramble. No, I didn't run the UEPrereqSetup_x64 first. It wasn't really clear what I should have run and in what order, I just assumed that $$$UnrealEngine was a launcher of some kind that would pick and install from the list of available apps in the archive. When I didn't get the Desktop 3.1.32 error after uninstalling the version found on the Microsoft link I assumed $$$UnrealEngine was running UEPrereqSetup_x64 and then Unreal_Engine_For_Aximmetry_2022_5.0 in sequence, installing the correct version of Desktop 3.1.32 along the way. Bar the errors at the end of the process in my last note Unreal Engine 5.0 is running. Should I uninstall everything and try UEPrereqSetup_x64 first? It would be great to get the authors input to determine how the install package should be navigated. Happy to go back to the start if its recommended and we can get it to install cleanly. 

Usually you shouldn’t have to install anything manually. The full Aximmetry installer should ask you if you also want to install the UE5 editor and will install all prerequisites for you. It does require an active Internet connection to download all the packages, so maybe something went wrong there?

That was our experience in the past with previous versions. We ran Aximmetry Professional DE 2022.5.0 on two different machines in two different locations on two completely separate internet services. Same experience in both locations. Aximmetry installs as expected, Unreal Engine 2022 5.0 does not. As mentioned in the initial post, Unreal directories are present but the application resources are not there. Presumably due to a conflict specific to the missing Desktop 3.1.32 run time during the online install over the internet. When downloading the Unreal build as a separate install to disk to fix the initial issue, it appears in an un-expected archive format with three separate install files and no instructions. As Aximmetry themselves haven't joined in on this post we've sent a note to support@aximmetry.com to try and determine what we should do next. eg: uninstall again and run a completely new install of everything, patch the missing .dll files or follow the same steps as above but follow your suggestion and install UEPrereqSetup_x64 first. 

The 3.1.32 shouldn’t affect installation at all. Besides, missing those dependencies was only an issue in the previous beta and should be fixed in the release version. I’m pretty sure there’s something else going on. Maybe a permissions issue?

.7z archives are very common now, both on Mac and PC, so I wouldn’t call it “unexpected”…. 

Any luck with this? We are experiencing similar issues

I had this same issue today.  I had uninstalled Studio DE a few weeks ago, installed the latest version today, and when I went to run Unreal for Aximmetry, it launched my old install of UE for Aximmetry 4.25.

I've reinstalled Aximmetry twice now, Unreal is still not there.  The 7Z file of just Unreal is downloading achingly slow (estimate is 8 hours).

Everything seems fine now that I installed the separate UE for Aximmetry download. I think the problem really was that there was no indication that UE hadn't installed.

Hi AsherJJB2023,

Did you manage to install Unreal? If not, which error message do you experience?

Warmest regards,
