Where exactly did you download the dmg file from?

Was it the mac app store?

I don't think so.

If you downloaded it from the mac app store it would have worked.

This, you have the wrong DMG...Dl from a reputable source and it will work fine.

Is the extracted file called "Install OS X Mavericks.app"
It needs to be exact.

I upgraded to OS X 10.9 (now have 10.9.2 installed); however some instructions as regards 'Download an OS X installer' are somewhat confusing.

The instructions indicate '...After purchasing and downloading OS X from the App Store, the installation program will automatically start. Instead of completing the installation immediately, quit the installer and make a copy of the OS X installer (copy it from the Applications folder to your Downloads folder)...'.

I do not have a disc to begin the process since I did the installation as a download direct from the store when I bought the program, but I do not see the OS X installer in the Downloads or Applications files.

Guidance and instruction would be most appreciated.

If you get Mavericks from the App Store and cancel the installation you will find the app, "Install OS X Mavericks" in your Applications folder.
If you don't then something is wrong and you might want to try downloading it again.
To use the sudo command listed in the very first post, it must be in the Applications folder and not the Download folder.

I always used Disk Utility and copied it to a flash drive using the Installer.dmg

That works too but according to MacWorld, that method won't make you a restore partition.

Here's a rundown of three methods.
