Keyword: XPS, GUI, icons
On my laptop I first installed EDK9.1i, but no help files were installed and I was missing Icons in all the nonstandard Windows buttons in XPS. Also, no buffers or connections are visable in the System Assembly View window.
I tried reinstalling EDK, but it didn't help.
Upgrading to SP1 doesn't solve it either.
Please make sure that you start up XPS with the correct executable, which is <edk_install_dir>/bin/nt/xps.exe.
This issue has been seen when you are using <edk_install_dir>/bin/nt/xpsgui.exe as the executable.
