How do I get the logs of installation

[testuser]

Thanks!! please check if it is possible.

However I was trying to use /E switch but it was not generating the log file, please find the attachment for it.
Just to let you know if following things have impact on logging:
1.My application UAC level is asInvoker
2.Command prompt is not run as admin
3.I was checking txt log file at c:\
4. I have tried forward and backword slash for E

am I missing something?
