What should I do if the installation of pico4 Stream Assistant shows an internal error?

The reason and solution of the internal error in the installation and display of pico4 streaming media assistant: 1, UG software thinks that the setting parameters are wrong, ... When the internal error dialog box appears, it can be considered that the function is working, but there is no way to delete the function at this time. 2. When modeling, the thinking is not clear enough, and one diagram is often changed to another, which leads to the complexity and huge graphic data, which is also easy to happen at this time. 3. Or open the directory C: \ Documentation and Settings \ Administrator \ Local Settings \ Application Data \ Unigraphics Solutions \ NX, and there is a DialogMemory.dlx file. After deleting this file, UG will start and close normally in the future.
