Hello friend!
Because we do not have your detailed information, we recommend that you perform the following steps to rectify the fault:

2. Check whether the installation procedure is correct. For details, see the following link:

3. Check whether the database software is running properly.
If the above check does not have any problems, you may need to reinstall the computer operating system, of course. Ensure that your PC does not have antivirus software such as Python and 360, decompress the software package again, and reinstall the software.
Good luck!
