It is possible when attempting to uninstall SlingPlayer Mobile for Windows SmartPhone from your Windows PC that you will not be able to do so.
The initial error I received was the fact that ActiveSync was not installed. The details of the error are below.
ERROR: SlingPlayer Mobile For Windows Smartphone – InstallShield Wizard
ERROR: Microsoft ActiveSync is Not Installed. Please install Microsoft ActiveSync 3.8 or greater to continue Installation.
I went ahead and attempted to uninstall Slingplayer Mobile after I installed ActiveSync and was still unable to do so as it was now requiring that I have my SmartPhone connected via ActiveSync. The problem for me was the fact that I no longer had this SmartPhone so it was impossible to connect it. I decided to go ahead and force uninstall the application using the Revo Uninstaller which is a totally free application.
Download and install the Revo Uninstaller. Once installed run the application which will then provide a list of all installed applications on the Windows PC. Choose SlingPlayer which will then trigger a series of steps where you will eventually remove the registry entries and files from the PC. Reboot your computer and SlingPlayer will finally be removed.
