Diana, Glad you got it working. I'll continue to look at the possible cause of this as it may create problems with reinstallation. Likewise, you should bear this in mind if there are any future upgrades. Waldo, The zip file format is universal, so there's no difference between any OS's or zip utilities. The zip file does decompress on XP without problems. All the indications are that you still have a file that was corrupted or prematurely terminated during download from the site, and the only real action is to download it again. Let me know if you still have problems. As I said earlier the first basic test is that the download file size should be about 400K. Bill
