Thank u konard and thomas
yes i tried with log also,actually trying to build an app that installs multiple app like ninite but in offline mode...and im succeeded too...but the only prob is im getting installer basic UI(switch /qb) when the selected apps start installing.
switch /qn is not working where with same command line switch /qb is working.
strAppltn1Path="msiexec /i"+"\""+@"absolute path\App1.msi"+"\""+"/qb/quite
/log install.log";
sw.WriteLine(strAppltn1Path);
Writing this above command into batch file..this above command works fine but when i change /qb to /qn it doesnt..
