  • Thanks a lot Muddassir for trying to solve my problem. I have tried all the procedure you have stated above but nothing works. Is there any other option to do to solve this issue or Format and reinstalling Windows 7 is the last option.

  • Have you installed a new computer and transferred the data from your old PC or laptop from it to new PC? Check whether your Internet Explorer needs updating. Update it to the latest version - I guess IE 11.
    Are you using Internet Explorer to open image files ? Even in the that case updating you IE may solve the issue.
    If the error specifically comes up with IE, your concerned .dll file has been unregistered or corrupted. If it is unregistered, you can get it re-registered . To do this ,
    Run as an administrator and open command prompt. Type: regsvr32 ExplorerFrame.dll and press enter. Once it completes the procedure, restart your PC.
    Whenever you get a "class not registered " error , check the title or the heading of the dialog box. It will indicate which program or file is damaged. That will help you narrow down your search to find the exact problem area rather than reinstalling the complete system.
