Steps to Reproduce
I have been trying to install MetaHuman for Maya plugin and I am unable to install it from Epic Games Launcher. I have Unreal Engine 5.7.4 and Maya 2025 installed. I am receiving error: IS-EO-Lnc_BldInfo:Http-403
I have tried disabling my firewall, as that is what is coming up what a 403 error is. Disabling firewall isn’t producing a different result. I have tried clearing cache in AppData>EpicGamesLauncher>Saved and deleting the folder called webcache_4430 which is associated with cache. I have tried running Epic Games Launcher as administrator and I have tried running UE as administrator. To try and bypass the issue of being unable to install from Launcher, my coworker has sent a zip file of MetaHuman file to try and install the plugin in UE and Maya. UE isn’t able to see MetaHuman plugin, even after directing the plugin. When trying this in Maya, I get 3 errors when trying to direct the plugin in the plugin manager.
The 3 errors I receive are:
Error 1:
Lib issue: ‘dna’, found ‘N/A’, expected ‘9.4.4’
A plugin that uses an incompatible version of the specified library is already loaded. This version is incompatible with the current application. If you’ve used a related external tool, the issue may be caused by a plugin associated with it. To ensure compatibility, please uninstall any plugins using an incompatible version of ‘dna’.
Error 2:
Lib issue: ‘dnacalib2’, found ‘N/A’, expected ‘3.2.1’
A plugin that uses an incompatible version of the specified library is already loaded. This version is incompatible with the current application. If you’ve used a related external tool, the issue may be caused by a plugin associated with it. To ensure compatibility, please uninstall any plugins using an incompatible version of ‘dnacalib2’.
Error 3:
Lib issue: ‘rdf’, found ‘N/A’, expected ‘6.3.5’
A plugin that uses an incompatible version of the specified library is already loaded. This version is incompatible with the current application. If you’ve used a related external tool, the issue may be caused by a plugin associated with it. To ensure compatibility, please uninstall any plugins using an incompatible version of ‘rdf’.
When the errors are done, I get this error in the script editor:
// Error: MetaHumanForMaya : Library ‘dna’ could not be imported.

All correct files are there and I was not able to find any files that may be fighting with MetaHuman for Maya.
I have tried this on two separate computers with the same result. The second computer is brand new and set up as a new computer with no preferences saved from previous computer. OneDrive is disabled as of computer setup. I have also tried installing different plug-ins from Epic Games Launcher, but I am also receiving the same IS-EO-Lnc_BldInfo:Http-403 error with different plug-ins. I have tried this also having Unreal Engine 5.6 installed, but have the same issues.
Expected Result
I expected the plugin to install normally.
Observed Result
Launcher seems to have a bug along with either MetaHuman or something that is bridging UE and Maya.
