The “add clause” will help in some instances most likely not in this situation…
For @renehasp 's instance, it would probably have to be the following for it to work.
OS include Win
and
Software 1 not on ver 111
or
Software 1 not on ver 112
or
Software 1 not on ver 113
It would be nice to be able to mix and match AND and OR enclosed in parenthesis but I don’t believe that is available out of the box.
I coudl be wrong but as an alternative you will probably going to have to write your custom relevance where you can enclose statements within parenthesis.
Then in that case, the analysis would need to be customized to get the result based on OS before it hits the web reports. The only other way I could think to do it is via session relevance where the request is customized.
This is a REALLY rough write-up but something along these lines:
(names of it, values of bes property "software 1" whose (value of it is not "111") OR values of bes property "software 2" whose (version of it is not "111") OR values of bes property "software 3" whose (version of it is not "111") of bes computers whose (operating system of it contains "Win")
There is probably a much better way to do it but hopefully that gets you started.
