Unable to add a program with file default open mode

Today reinstall the next VIM software, and then set some file default open mode, found unable to specify them to vim open, in the open mode list can not add Vim program, later Baidu a bit, just know the reason, is green software reinstall, the software path changed, But the file path in the registry has not changed, the workaround is to modify the registry path, as follows:
"Start"--"Run"--enter "regedit" point carriage return--find "hkey_classes_root\applications\ specified program. Exe\shell\open\command"-- Change the original path in the registry key to the current path--save exit--solve the problem.
