For First-time Users It is recommended that Adobe Acrobat Reader be installed before installing CD Sheet Music. For optimal performance, versions of Adobe Acrobat Reader prior to 4.0 should be removed. For future use it is not necessary to reinstall either Adobe Acrobat Reader or CD Sheet Music. Simply launch CD Sheet Music directly, using the "OPEN" Command button on the startup screen, or use the Desktop Shortcut/Icon. Newer versions of CD Sheet Music are compatible with all older versions. It is not necessary or recommended to uninstall older versions of CD Sheet Music as the new versions overwrite the older Desktop Shortcut/Icon. Newer versions provide enhanced functionality. HELPFUL HINT: To navigate more easily through the CD Sheet Music files, simply go to FILE/PREFERENCES/GENERAL and uncheck the option box for "OPEN CROSS-DOC LINKS IN SAME WINDOW." This will allow you to keep your position in the table of contents. This function can only be achieved after Adobe Acrobat Reader is installed. More Questions?
