I have been getting this error message (Error 1720)whenever I try and install anything new for the past year or so. I am once again having this issue as I am trying to reinstall my incredimail. I have been on the microsoft site all morning and have run scans, fixes etc. tried just about everything over there but nothing is working, now they told me to come to Dell.????
