Cannot uninstall OpenCL 1.5 SDK after Windows 8 upgrade

Cannot uninstall OpenCL 1.5 SDK after Windows 8 upgrade

After upgrading to Windows 8 I am unable to uninstall the 1.5 SDK - the installer tells me the OS is unsupported. Is there any way to force the uninstall, or to manually remove the components?

For manual removing try the following (for 64-bit OS, I guess it's easy to convert to 32-bit one):
- delete folder C:\Program Files (x86)\Intel\OpenCL SDK\1.5
- delete environment variable INTELOCLSDKROOT
- edit PATH environment variable to remove the path(s) to C:\Program Files (x86)\Intel\OpenCL SDK\1.5\bin\x86|x64
- delete registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Intel\OpenCL

If you don't have any other OpenCL platforms installed you may also remove:
HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors
c:\Windows\System32\OpenCL.dll
c:\Windows\SysWOW64\OpenCL.dll

Thanks - I gave it try. Hopefully this will allow me to run the 2.0 SDK installation.

Okay I did all that and rebooted. The OpenCL driver chain still thinks the Intel OpenCL driver is installed - this means when I run any OpenCL program it crashes because it cannot find the Intel OpenCL library components I deleted manually.

I need to remove the Intel OpenCL ICD from the list of ICDs, so it won't attempt to use it. Any idea how to do this?

You can remove the following registry keys to rectify the crash:

For 64-bit systems:

HKLM\Software\Khronos\OpenCL\Vendors [IntelOpenCL64.dll]

HKLM\Software\Wow6432Node\Khronos\OpenCL\Vendors [IntelOpenCL32.dll]

or for 32-bit systems

HKLM\Software\Khronos\OpenCL\Vendors [IntelOpenCL32.dll]

Great working now! Also installed the 1.2 beta driver.
