Sorry for the delay in getting back on this, but I had a few things to do. I did a search on my PC to see if any of the files are listed as being installed
libEGL.dll shows as being installed in several Reallusion product directories.
libGLESv2.dll shows as being installed in several Reallusion product directories.
d3dcompiler_*.dll turned up several instances of d3dcompiler_47.dll that is installed in both the iClone and Character Creator directories.
My only suggestion at the moment would be to uninstall your Reallusion products and reinstall them. It is possible that you have corrupted installations. It may even be a good idea to redownload the installer files from your Reallusion account just in case the ones that you have are corrupted.
