Now,I have followed all the instructions,but when addon is placed in the driver update in nlite,it doesn't install,what I'm doing wrong here. It's little confusing to me,as to,where I actually place the 'NoLic.mst' ?,secondly,after extraction and replacement of 3 files,as explained above,do I have to repack it or ? or how do I again create a silent inataller with the extracted msi folder. I'll just explain here a little what I have done:- 1. Extracted MSI (WISDED53B0BB67C4244AE6AD6FD3C28D1EF_7_0_2_5.MSI) to a folder containing the following :- 3 folders (Application Data,Program Files,Windows) Windows Installer Package (WISDED53B0BB67C4244AE6AD6FD3C28D1EF_7_0_2_5) of 3,209kb Replaced the 3 files ( core.aawdef PubKey.key settings.aaw to the "Application Data\Lavasoft\Ad-Aware 2007" The, Placed the 'NoLic.MST' in the folder containing all 3 files and Windows Installer Package. Made a winrar archive(Ad-AwarePro_v7.0.2.5.MSI),put it in 'SVCPACK' and alongwith 'ENTRIES' config setting with the following:- [AddProgram] msiexec /i Ad-AwarePro_v7.0.2.5.MSI /qn TRANSFORMS=NoLic.mst Integrated with nlite,but upon windows installation,it didn't get installed at all ? Now what and where I'm going wrong or what shud I do ? Do I have to repack the the folder containing 3 files,windows installer package and nolic.mst file or ? How do I create a Silent Installer ? Kindly explain in detail to help me out, thanks
