1. In the installation folder you will find a file @ AIAFPackSetup\Disk1\install\oraparam.ini
As of now the installation is supposed to work till windows XP.(version 5.2). Vista being 6.0 will not allow AIA FP to be installed
The line will be like this
#You can customize error message shown for failure, provide value for CERTIFIED_VERSION_FAILURE_MESSAGE
Windows=4.0, 5.0, 5.1, 5.2
So you need to edit and add 6.0 to the windows versions.
Windows=4.0, 5.0, 5.1, 5.2, 6.0
The same issue is there with other oracle SOA suite installation also.
2. AIA installation will extract all the installation files to the AIA home that we specify during installation. The executable file will be using ant scripts to complete the installation. So if your installation is failing at any point refer to AIA_HOME\logs\install.txt . If you are comfortable with using ant you can manually modify the ant scripts to complete the installation.
3. OSR and AIA installation will be deploying registry.ear and AIAApplication.ear respectively into Oracle application server. So easiest way to crosscheck whether your installation succeeded is to check whether these ears are deployed in the Application server.
