Having Trouble While Working on this Software

Hello everyone, I have been having a problem for a few days that I cant seem to solve it anymore. I recently installed this software. But for a few days I am having a problem when I am working on this I received this error message "explorer.exe class not registered." I have no idea about this issue. Could someone please help me to solve it? Any kind of help would be greatly appreciated.
