kdbsync.exe Crash Error - Solutions to fix the problem

kdbsync

The problem will be also detected by Gpu-Z (opencl64 bug).

Workaround (not suggested)

We can remove the registry key so that it will not try to start at all

32 bit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\AMD AVT

64 bit
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run\AMD  AVT

 -possible value in the registry-
Cmd.exe /c start "AMD Accelerated Video Transcoding device initialization" /min "C:\Program Files (x86)\AMD AVT\bin\kdbsync.exe" aml

This solution will not give you a set of features (as for the name "Accelerated Video Transcoding") but you will not notice the difference from before.

Solution

Reinstall the AVT and OpenCL.
Remember to close GPU-Z and any other application that can use OpenCL.

Sample path for the already installed drivers. It could also be within X:\ATI\...
(AVT)
C:\AMD\Support\12-10_vista_win7_win8_64_dd_ccc_whql_net4\Packages\Apps\AVT64\AVT64.msi

(OpenCL)
C:\AMD\Support\12-10_vista_win7_win8_64_dd_ccc_whql_net4\Packages\Apps\OpenCL64\OpenCL.msi

If you don't have those paths just download the drivers and unpack them.

It's possible that a different version of OpenCL.msi will not let you (un)install over the older version.
