i have download latest AMD driver for my ATI Radeon 6370 for win7 x64 at this link:
https://www.amd.com/en/support/graph...adeon-hd-6370m
then on Catalyst Software Suite have whql-win8.1-win7-catalyst-15.7.1-oct30.exe file.
i have extract this file on C:\temp and have WHQL_Catalyst_15.7.1 folder.
on this folder only driver to update my graphic card is into: Packages\Drivers\Display\WB6A_INF....
but installed (update) this driver, i have only VGA driver installed, not properly ATI Radeon driver.... and same behaviour with run whql-win8.1-win7-catalyst-15.7.1-oct30.exe (install video driver only)...
then i come back to prevous C: image with true image.
