Before installation change the server mode to install. c:\>change user /install
After installation change the server mode to execute. c:\>change user /execute
While restarting the server reboots in execute mode. So if the application reboots in the middle of the process (Mid-Install process) then we have to plan according to that.
The application writes in Run or Run Once in Machine or User registry keys. So remove the keys from the registry before restarting. After booting the server continue the installation after changing the terminal server to install mode.
TS Application Analyzer Microsoft tool used to analyze the application whether it is compatible with the Terminal Server.
