Sage has just published their official Windows 7 compatibility chart. Based on the document it appears that the MAS 90 product line (Sage MAS90, MAS200 and Sage MAS 200 Extended Enterprise) will become Windows 7 compatible sometime on or about March 2010.
Although the document conveniently omits stating whether the compatibility will be with 32-bit or 64-bit Windows 7 versions – we recommend sticking with 32-bit for the time being.
