Just to verify...
A client is asking if all the workstations are now Win 7 Pro except for one Vista that they still want to use with Adagio.

Will we still be ok if we bring them up to V9.2A?

Are you asking if there is any known issue running Adagio 9.2A under Vista? While it is not specifically tested, there is no specific reason there would be a problem.

Yes, I am asking if there are any issues.
The client has not yet updated to V9.2, and we want to ensure that Adagio will keep on working at their site, seeing that one of the computers is running under Vista.
Andrew, you have provided the answer - "there is no specific reason there would be a problem".
Glad to hear. Thank you.

It is not specifically tested, and, should there be an unforeseen problem, it would be less expensive for them to replace the Vista machine than to try and troubleshoot the "why?".
