This is because you need to do something similar to Windows Update to avoid the trouble of running around when the program is updated. Although there are many similar tools, most of them are complicated, so you decided to create a similar simple program by yourself.
Compare the client and server program versions, and copy the new version of the server program back (Using VPN, equivalent to copying files in the LAN), but there is a problem with installing the new version of the program, if you find a previous version of the Windows Installer installation program, you must delete the old version of the program and reinstall it. However, you must uninstall and install the program automatically. If an error occurs when running the MSI file directly, I will wear the parameter. If no relevant information is found, I guess the uninstallation should be/U. If it is not uninstalled during the operation, a dialog box is displayed, windows Installer parameter settings: Windows (r) installer. V 3.01.4000.1830

I tried this parameter many times (I am stupid) and finally succeeded. Paste the code below. The program name to be installed is clock. msiusing system;
Using system. diagnostics;
Public class maintest
{
Public static void main ()
{
// The Windows Installer command is msiexec
Processstartinfo startinfo = new processstartinfo ("msiexec ");
// Uninstall program parameters
Startinfo. Arguments = string. Format ("/uninstall clock. MSI ");
PROCESS p = new process ();
P. startinfo = startinfo;
P. Start ();
P. waitforexit ();
// Installer Parameters
Startinfo. Arguments = string. Format ("/I clock. MSI ");
P. Start ();
P. waitforexit ();
If (P. hasexited)
{
// Start the newly installed program after installation.
Startinfo = new processstartinfo (@ "C: \ Program Files \ Spider \ clock \ clock.exe ");
P. startinfo = startinfo;
P. Start ();
}
}
}
