outlook question

[ADO DOT NET]

I want to use and include the Outlook 2007 COM Library Reference in my program.

I think my program won't run on systems that haven't Outlook 2007 installed.

That won't make any problems for me.

 

1. My question is how can I detect that Outlook 2007 is installed on a system?

Somewhere in registry?

 

2. And also how should I show a proper error message box instead of crashing error when my form loads on a system without outlook?

thanks

Does it really need to be outlook2007?

 

1. You can search the machine for the outlook folder. It is usualy in "C:\Program Files\Microsoft Office\OFFICE11\OUTLOOK.EXE"

2. You can search the registry for an entry for outlook.

 

For your message;

"This application needs Microsoft outlook 2007 properly installed to run." <-- is this OK?

 

As to the HOW to show the message.. you can of course use the messagebox AFTER you detect if outlook is present or not.
