I found a workaround that allows the editor to work in Windows 10 64-bit.
If GraalEditor.exe loads d2d1.dll and/or d3d11.dll in C:\SysWow64 it causes the crash on open and iertutil.dll which causes the file dialogs to crash.
Blocking access to the dlls allows it to run properly.
To safely block access to those dlls:
1. create a second user (e.g. test) with a password and configured a runas batch script:
2. changed ownership of the dlls to administrators
3. set deny full control to test user
Editor.bat:
PHP Code:
runas /env /user:test /savecred "GraalEditor.exe %1"
Then configured my .nw files to open with the batch file:
