The viewer launched after saving the output is wrong ? Settings ? where ?

Since the last update, after saving the output, the "viewer" launched (should be by default PdfArchitect) is something else ? it starts VirtualPC.exe on a Win7-64 sr2 system !!! which crashes...

Where are the settings ?

I remember that, some years ago, with the beginnings of PdfArchitect I had changed it to AdobeReader (lighter), but recently with last versions I have not changed anything.

I don't remember where was this parameter and I have found nothing into the "lang".ini file.

Thanks

Note1 : I uses the French version. 1.07.0003

Note2 : During two hour I tried to send the message refused by an _xml_ error which come form the system imagination... I cut my remark about this subject to try to send the message 

So I wait 600 secs between tries.

and need more than one hour to send it.
