Need to get files other than the standard .exe files into your inventories. Perhaps the programs you need to inventory do not have .exe files such as ActiveX Controls.
These can easily be added in by using the Audit Plus Configuration Editor that is part of Inventory Solution. By default it is found in this folder on your Notification Server: Program Files\Altiris\Notification Server\NSCap\Bin\Win32\X86. Run AexAPedit.exe and click on the File Masks tab.
The instructions there show that you can only enter in file types such as *.DLL or *.OCX. You can also enter in full filenames. A good example is "flash*.ocx". This inventories the different Flash Player files that will let you know what versions of Flash Player you have installed.
We use this quite extensively and can then build Software Delivery jobs and other tasks against the resulting data since it all gets stored in the Inv_AeX_SW_Audit_Software table.
