double-click Add/Remove Programs, and select an installed program to remove or
update, you get the following error message:

Uninstallation has been cancelled
If you rename the folder called Program to, for example, Program2, you see the
following message:
This change may impact one or more registered programs. Do you want to
continue?

UninstallString:reg_sz:"c:\Program Files\My_program\setup" setup
UninstallString:reg_sz:c:\Progra~1\My_program\setup setup
