I created a brand new installation of Windows 10 64-bit Enterprise running on VirtualBox.
Card: AMD Radeon R7-200 series
I downloaded the amd-catalyst-15.7.1-win10-64bit.exe driver.
The Installation proceeded to the main setup program an just past the accept terms, I received a 1723 error.
Event Viewer: (Windows Logs | Applications)
"Product: AMD Catalyst Install Manager -- Error 1723: There is a problem with this Windows Installer package. A DLL requird for this install to complete could not be run..
Action: SetInstallDir. entry: SetInstallDir. librarv: C:\Windows\Installer\MSIA7C6.tmp"
The MSI installer created the "C:\Program Files\AMD\CIM\Config" folder and that is about it. The folders are empty.
