The full warning message is:
"It is not absolutely safe to uninstall the application. The application may turn to be not completely removed from the VPS or some related files inside the VPS may be corrupt. Are you sure you want to uninstall the application?"
This message is a standard message SW-Soft uses for any application that might not remove every file when you uninstall it. You must click on the OK button for HSPC to remove that application template from your VPS.
