I read "finishing install". So it should be finished now (if we may believe the message which isn't always true, alas). What happens if you send another page? Same message? Or was it a one-time only message.
If it was one-time only I wouldn't mind. If it's recurring and recurring, it's a potential issue. Did you do anything with your system recently, that might be related (such as installing the cumulative update for IE that came with Windows update last Tuesday, or updating your email program)?
Windows XP SP2, I want to send a web page by email. I click file, send, send page by email, I get this message... A previous installation did not complete correctly. Finishing install. Any advice?
