I am sorry to say that performing the steps you detail above still has not solved the issue.
It has the ffect of removing the item from the context menu and then adding in to the context menu again but still when I click on the item in the context menu nothing happens.
I do have other items on my Windows context menu that work OK – for example a free text editor I used before finding emeditor called pspad.
Alternatively, you can try this:
1. Make sure you removed the original EmEditor menu item by going to EmEditor > Customize > Shortcuts > More Shortcuts.
2. Run regedit.exe.
3. Add HKEY_CLASSES_ROOT*shellEmEditor key.
4. Add HKEY_CLASSES_ROOT*shellEmEditorcommand key.
5. Set the default value of HKEY_CLASSES_ROOT*shellEmEditorcommand as “”C:Program FilesEmEditoremeditor.exe” “\%1″”
I hope this helps.
