corrected setup.ini with
proper path to redist subfolders ( was named support, in original )
Code:
[LauncherSettings]
InstallRedist=1
Launch1=DirectX
Launch164=0
Launch1BeforeInstall=0
LaunchCom1={src}\Redist\DirectX\DXSETUP.exe
LaunchArg1=/silent
Launch2=PhysX 9.12.1031
Launch264=0
Launch2BeforeInstall=0
LaunchCom2={sys}\msiexec.exe
LaunchArg2=/qn /i "{src}\Redist\Physx\PhysX-9.12.1031-SystemSoftware.msi"
Launch3=Visual C++ 2008 SP1 x86
Launch364=0
Launch3BeforeInstall=0
LaunchCom3={src}\Redist\VC80\vcredist_x86.exe
LaunchArg3=/q
FINALLY got some spare time to test this installer & noticed the error in setup.ini, funny I missed it alltogether when updated Physx to latest version for you
