This morning I returned to my computer and found that it had been restarted because Windows Update installed updates KB977074 (important for Win 7 x64 system) and recommended update KB978506 (IE 8 compatibility view list for Win 7 x64). I don't know whether I had left Outlook 2007 open or not because I wasn't expecting updates to be installed. Since then I have not been able to open Outlook. It starts to open, but then I get the message "Cannot start Microsoft Office Outlook. Cannot open the Outlook window."

I tried to repair from my Office CD, but it didn't say there were any problems. I was going to uninstall Outlook, but it appears from the CD that I have to uninstall all of Office, which I didn't want to do. If I uninstall, I don't want to lose my pst folder.

I upgraded from Vista a couple of weeks ago and have been receiving a lot of different updates with no problem.

Any ideas to restore Outlook?

I have the same problem. Have Windows 7, Office 2007 and all worked well until this afternoon when i installed update KB986422 and from then on get the message Outlook cannot open Outlook Window. I did system restore twice. Did Office repair twice. Uninstalled office and reinstalled it and still get the problem. I've searched for Outlook.exe and it seems not to be on my computer even after my reinstall. Searched for outlook.exe/resetnavpane and am told it doesn't exist! What can I do now????

Have you typed the command properly?

There is a space in between “Outlook” and “/” and no space in between “/” and resetnavpane.

Try and check if it works.

Same problem for me. Same solution worked although I did have to force Outlook to close with task manager beforehand.

system restore will not work and neither would removing the specific updates associated with this particular problem. There were two updates that came in that caused this bleep in the past couple of days.

Hi Surya, I tried this but still no luck. I get exactly the same message. I'm using windows 7, office pro 2007. I have had no problems with Outlook before. I can open all other office programs, and only can't open outlook. I can open outlook in safe mode. Thanks mate.

Try to create a new Outlook profile using the steps givenhere then reconnect the old PST and configure the email account.

Also provide the exact error message displayed on the screen and detailed information regarding the issue if problem persists.
