GPU application version is available for beta-testing now. Both AMD and NVIDIA GPUs are supported. 1 GB of video RAM is required. To test it, enable "Run test applications" in project preferences here: https://sech.me/boinc/Amicable/prefs.php?subset=project

I know the app is curently in beta test and that can be a bug but I really want to know why that won't run on it.

It fails to compile:
can't enable all OpenCL extensions or unrecognized OpenCL extension
#pragma OPENCL EXTENSION cl_khr_global_int32_base_atomics : enable

Try to update drivers. If it doesn't help, then AMD HD 4xxx just can't run this application.

Ok thanks you. But no update available everything is up to date.
It seem need a 5th gen (HD 5000) to work.
