Don't reverse it, you can usually pay normally. If not, please install MSXML together! The new version of CITIC Payment Control perfectly supports 64-bit WIN7! If you can't pay normally, please open Windows Update to update the system to the latest status! If you still can't pay, it may be that the control you downloaded is incomplete or there is something wrong with your system that needs to be repaired! It is best to reinstall the system with genuine WIN7 CD, and update the latest status when installing the above runtime!
