Everyone can open the uploaded courseware, but the courseware can't be opened on the intelligent education platform because of adaptation problems and network connection problems.

1. adaptation problem: the intelligent education platform may not support some documents with special formats or may need some special extensions or plug-ins to run some courseware normally. You can try to convert the document to a more common format, or upgrade or install adaptive extensions or plug-ins.

2. Network connection problem: If you can't connect to the network or the connection speed is slow, it may take longer to download or fully load the courseware, which will also lead to the problem of not opening or opening slowly. You can try to check your network connection and choose a more stable network environment as much as possible.

Unable to solve the problem, please consult the technical support of your school or smart education platform for more detailed help.
