[Windows 10 Mobile] getmeglance:
EDIT: It is now working, thanks for making me double check my method. Stumbled upon the solution while searching for ".dll" in this thread. Turns out I had to replace the backwards double slashes with backwards single slashes from the .reg files (values that contain the keyword "path"), which I did not know that needed to be done. Thanks to this post.

Thanks for your reply. I have used Interop Tools Beta 1.9 Pre-release 9. I have copied the missing files to

Data/SharedData/OEM/Public

The files and folders I copied are:

lpmFonts_4.1.11.3
lpmFonts_4.1.12.4
NsgGlance_NlpmService_4.1.11.3.dll
NsgGlance_NlpmServiceImpl_4.1.11.3.dll
NsgGlance_NlpmServiceImpl_4.1.12.4.dll

I have uploaded the registry keys directly via Interop Tools on my phone. These are:

I have checked that these are indeed written to the registry using the registry browser of Interop Tools. Can't see where I might be missing something. When you say

you mean importing the registry keys, right?
