Q:

BizTalk AS/2 implementation certificates

I cannot add any certificates on AS2 messages in BizTalk. 
So here's what I have for the moment (I have installed 2 certificates on the BizTalk machine using the same account as the on under which the Host Instance is running. 
The 2 certificates are the following and placed in the locations:
\Personal\Certificates - My own certificate 'pfx'. 
\Other People\Certificates - Party certificate 'cer'. 
So far the importing of the certificates. 
Now, when in BizTalk Administration, I go to Parties and I go on the agreement between the parties.  In that window I go down to 'Signature certificate' and I check "Override group signing certificate".  Then when I click "browse" I see:
"No certificate available." 
"No certificates meet the application criteria". 
Any idea on what's wrong here? 

A:

I've found it.  The certificates should be installed under the same instance that the BizTalk Administration Console is openend.  Otherwise the certificates could not be found.
