Some different things you can try:
-
Restart your computer and try again.
-
Delete the key yourself.
-
Don't worry about it.
To uninstall Opera Mail manually, just delete:
"C:\Program Files (x86)\Opera Mail"
"C:\Users\user\AppData\Local\Opera Mail" (if there's no longer anything you want in it)
"C:\Users\user\AppData\Roaming\Opera Mail" (if there's no longer anything you want in it)
In the registry:
-
"HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\OperaMail"
-
"HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet\OperaMail"
-
Opera Mail strings in "HKEY_LOCAL_MACHINE\SOFTWARE\RegisteredApplications"
-
The key for Opera Mail in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" and or "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall" or search for it by searching the registry for operamail.exe.
-
The Opera Mail class keys in "HKEY_CURRENT_USER\Software\Classes", "HKEY_CLASSES_ROOT" and "HKEY_LOCAL_MACHINE\SOFTWARE\Classes".
Pretty much anything else you can leave behind. But, you can search for other OPera Mail keys and delete them. But, just because a key has a string that has a path to operamail.exe in it, doesn't mean its an Opera Mail key.
Or, in the Opera Mail program files directory (after you reinstall Opera Mail), edit opera_install_log.xml and remove the entry for key path="Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted", which may help the uninstall complete (if the uninstall isn't really completing for ya).
(forgive the formatting of this post. Forums has a lot of markdown styling bugs at the moment.)

hmmmm, i hate it when that happens:(
you already said it (and you said it didn't work) ... but i'll say try again ... reinstall it and then uninstall it. try to reinstall from a different source.
when you uninstall, use revo uninstaller (if 32 bit) or Advanced Uninstaller Pro (32 and 64) or wise uninstaller (32 and 64). they will scan for left overs to remove for you.
or use wise registry cleaner (advanced uninstaller pro also has a registry cleaner in it). scan system and look only for entries that say opera mail or something. only select them to delete. make a retore point first (you can make a registry back up with these two registry cleaners first/also).
one more possiblity: since opera mail is in opera presto. perhaps if you install the browser and uninstall it, it will remove the mail parts for you. this might get you around the problem you're having with reinstalling the mail program.
