Message when trying to install JooBB :
"Error! Could not find an XML setup file in the package".
Is this problem common or should I consider my configuration ?

Welcome. Did you download the package from our link found here? That is not a Windows 7 problem, the Joomla installer is telling you that it can't find the xml file that contains the install instructions.
If you did download our package, did you upload the entire zipped file? Don't unzip it first, upload the zipped packages individually.
You do need to unzip the entire package file, but then there are (4) other zipped files that get uploaded individually.
