I am running Q2015 Deluxe, but did NOT install R9 or the R10 fix. And now see on the Q forum some reports of probs with R10...
SO - now ready to install TTax Premiere 2015... but .... wonder if there are any install file conflicts between Q2015 and TTax2015 - A - without having either R9 or R10 installed B - needing R10 to be installed to fix the conflicts C - other ??
