Dear all I recently installed Autocad2000, Autocad 2000 Migration Assistant, Autocad 2000 Learning Assistant (all help files and video's are functional) using Longbow Software from The Longbow software installs Autocad 2000 which is completely functional in Windows 10 version 2020 including express tools and other Autocad 2000 updates needed. Longbow's software works very well. Windows 10 removed ability to open the old help files, I had to replace the windows 10 "winhlp32.exe" to get the help system to work, this was a bit involved but can be done via -to-open-hlp-winhelp-files-in-windows-10/
