Resolving “OLMAPI32.dll is incompatible” Error When Upgrading from Outlook 2007 to Outlook 2010

outlook 2010 splash screenYou cannot/should not, it appears, retain Outlook 2007 installed on your PC after upgrading to Outlook 2010.

If, as I did, you do not de-install Outlook 2007 after the upgrade you may find that you cannot run Outlook 2010. In such case you may get the following error message when attempting to run it:

“The file OLMAPI32.dll is incompatible with Microsoft Outlook. Install Outlook again”

It may be possible that had I uninstalled Outlook 2007 or had I never attempted to run Outlook 2007 after upgrading to Outlook 2010, this error may never have appeared. Nonetheless, once this error appeared I was not able to run Outlook 2010 again until I uninstalled Outlook 2007 as described below.

Note: As always, before proceeding, I recommend creating a restore point in case something goes wrong.

According to this Microsoft Answers post, the solution did not lie in ”Installing Outlook again’ as the error message suggested. Rather, the solution required uninstalling Outlook 2007 and repairing Outlook 2010.

So, off to Add-Remove Programs from the Control Panel to Remove Outlook 2007 right? Not so easy.

How to Get Rid of the Annoying Warning Message When Opening Attachments in Outlook 2007

grayed-out and checked 'Always ask before opening this type of file' box

If the warning above annoys you as much as it does me whenever you open an attachment in Office 2007, here’s how to get rid of it.

The Problem

Microsoft has understandably made security a cornerstone of its recent software releases. Each time you attempt to open a possibly malicious attachment in Outlook 2007, a warning dialogue box like the one above appears. It presents an always-checked, always-grayed-out box that reads: ‘Always ask before opening this type of file’.

Because Word, Excel, PDF and other document types can contain malicious code, you should, as the box warns, only open attachments from trustworthy sources. But, if you have a modern Anti-Virus program such as AVG or Microsoft’s Security Essentials (both of which are free), attachments in your emails should already be checked for malicious code. When this is the case, this warning dialogue box is an unnecessary interruption that becomes increasingly annoying if, like me, you receive emails with attachments many times a day.

The Solution in  Windows 7

Warning: You should only do this if you have anti-virus software installed on your computer that checks for, and quarantines, all emails that contain attachments with malicious code. And, as the warning says, you should never open attachments from anyone that you don’t know and trust! 

OK, you’ve been duly warned. Here’s how to do it:
