I have created applications which has 2 version - Trial & Registered. At present I have kept limitations on trial version & after the period is over, user has to register the product to use further.
But many uninstall the applicaiton & install it again which makes them free of access multiple times. I want to restrict this. If a person installs once the applicaiton, after finish of trial period, it should not be able to install again. How do I achieve this. I have no idea on how to achieve this or work around this. I need to know this for normal application & mobile application.
You put a value in registry like for trial you keep TRIAL
Now on uninstallation, dont remove this value, keep it in there secondly you can create a temp file in some windows or other folder that is hidden & read only, now if someone reinstalls the application, check the registry value & read that file, if its there then restrict installation.
