The cause of this error is: "When installingProgramWindows Installer verifies the digital signature of the package to ensure that the package is not tampered. In this case, the entire package is loaded into the memory, and the computer must have enough continuous memory required by the package size. If the computer does not have enough continuous memory, an error occurs. Due to an error, Windows Installer cannot verify that the package is correctly signed. "

Therefore, this problem should only occur on computers with less memory. For example, if I only have 1 GB memory and cannot afford the 454.7 MB SDK, this annoying problem occurs.

2. Run net stop msiserver in cmd to disable the window installer service. (Attachment: stop_msiserver.bat)
3. Run the installer
4. Fixed policyscope. (Attachment: resetpolicyscope. Reg)
