The command which I was running was as below

setup.exe configurationfile="C:\ConfigurationFile.ini"

Here is the error on command line.

I went back and looked into log (Detail_LandingPage.txt) files and found below.

Well, I didn’t find any documentation that I need to specify the value. If we look closer at the log, it seems that the value which is taken by the parameter is

Full,configurationfile=C:\ConfigurationFile.ini

Wait a second!!! it has parameter which I have specified. I looked into documentation and found that parameter name should start with “/” Since I have not specified the parameter name configurationfile with a slash. Same error can also happen if below is used

setup.exe IACCEPTSQLSERVERLICENSETERMS /configurationfile="C:\ConfigurationFile.ini"

In above, I have missed slash before IACCEPTSQLSERVERLICENSETERMS

Bottom line:  Check the setup Logs and find which parameter is not having correct value and what is the value passed and taken from setup.exe

Hope this helps.
