ACDSee can't open JPEG format picture How to solve

I have no way to view JPEG pictures with ACDSee. I have used the Windows 2003 Server SP1 system and have upgraded the system to the latest. My ACDSee is using version 7.0. I uninstalled ACDSee many times and still can't solve it. Give a trick!

A: This problem should be caused by the incomplete installation of ACDSee, and if you uninstall it is not complete, it will not solve the problem if you install it several times. First uninstall the uninstaller and then delete all ACDSee folders on the hard drive, including "C:\\Program Files\\ACD Systems", "C:\\Program Files\\Common Files\\ACD Systems", "C:\\Documents and Settings\\" All Users\\Application Data\\ACD Systems" and "C:\\Documents and Settings\\username\\Application Data\\ACD Systems" (assuming the default installation, where username is the username you are logged into the system). Then type "regedit" in "Run", press Enter to open the Registry Editor, search for the string "ACD Systems", delete all the found results; then search for "ACDSee", the key value will be found Also delete all, and finally enter "My Computer" - "Tools" - "Folder Options", select the "File Type" tab, delete the association of JPG, GIF and other image formats. Finally reinstalling ACDSee should solve the problem.
