I'm operating on Windows 7, and when I install adobe reader, it tries to open everything in adobe, including IE, Mozilla, word, etc, which results in not being able to open these applications. All of the icons on the desktop have the appearance of a pdf file. I have seen on other help boards that other people have experienced this problem, but none of the suggestions have solved mine. The only way I have found to remedy is uninstalling adobe, which allows me to return to normal, but of course I can't view pdf files. Any suggestions?
