Have Vista Home Premium on new computer. Since transferring my Office 2003 SB Suite, I can not open attachments. This includes file types such as above that are not on the list of forbidden file types. I can save them and turn them into objects in word, but they are mostly a mess- hex code with some english, no formatting. I've added the Level1 parameter to my registry with these parameters as arguments. That hasn't helped. I do not find a "don't open attachments" checkbox that I can uncheck in the security tab of options. Can anybody help?
