I need to enable silent execution of an InstallScript Project. It is more of a wrapper installer/script for another InstallScript MSI Project . This wrapper Installscript is required to run some DB scripts and then trigger the product msi silently .
There is a new requirement to run this installscript as well in silent mode. Properties like uiLevel cannot be accessed using MsiGetProperty . I just ran the installer through command line /s /v"PARAM1=TRUE /qn" . It did nothing and did not even create the log file in the temp dir

Since there is no InstallSequence defined. How do I even direct it to any new custom action that I write for Silent Input Validation ?
