No dice on the above... not a valid win32 application.
Dug into the Windows error report and it seems to be something with the amdocl.dll
EDIT: Found out why.
For Win 7 64 you do not use the system32 folder... you need to rename amdocl.dll in the SYSWOW64 folder and then add the one linked here.
Working now... time to tweak!
EDIT2: Of course... this has now broken my cgminer for scrypt mining unless I swap the files back... NICE!
yeah figured as much, march=nocona is core generation intel, I didn't have a dll issue at all and can switch between the two easly, must be a driver/sdk issue
using driver 13-12_win7_win8_64_dd_ccc_whql, AMD-APP-SDK-v2.9-Windows-641 and cgminer 3.7.1 on r9 280x, win7 64 basic.
