I am having problems installing the 2013 beta version of the OpenCL SDK, on Windows 7 with VS 2012. I have a sandy bridge core 17 processor. When I tried to install the SDK, it reported a crash, then backed out changes, but OpenCL no longer works. I have tried to reinstall the 2012 version, but it says there is a more advanced version installed, and I must uninstall that version. However, neither version shows up in the Control Panel uninstall programs list. When I try running the 2013 installer again, it says "The installer identified that the installed version of the CPU only runtime package is broken. Try removing it, or contact the product support at" this forum. I uninstalled the CPU only runtime, but it still gives me that message.
Is there a manual procedure for uninstalling the SDK?
