How do I programattically check whether a user has the Redemption.dll file
installed on his machine?

I want to do this:

1. Check if Redemption.dll is installed on machine
===> HOW?????

2. Check if in Outlook Proyect, Redemption add-in is referenced to
===> HOW?????

3. If so, use a procedure with redemption methods (without security prompts)

4. If not, use a "normal" procedure (that will trigger security prompts)

TIA

The easiest way to do that is to try to create a Redemption object and catch
the error if it is not available.

Hi Dmitry,

but if the user has changed the progid (and he should do that) then this
isn´t possible, is it?

@Martin: I´d say, buy the dll and distribute your project with it. That
is the surest way :-)
 
Correct. If the prog id is modified (customized), you can't use the
customized version unless you know the new class names/class GUIDs.
