I have SQL Navigator 5.0 on my machine I want to upgrade to SQL Navigator 5.5. Do I have to inst (4299867)

I just received a notice to upgrade to SQL Navigator for Oracle version 5.5.0.713. I currently have release 5.0.0.607 installed on my PC. I know
there was an upgrade prior to the current one. Do I have to install the prior one before installing 5.5.0.713?

SQL Navigator 5.5 in not a patch for previous versions of SQL Navigator. You do not need to have prior installations of SQL Navigator on your machine to install this version. SQL Navigator 5.5 will prompt you to install the software in a SQL Navigator 5.5 Default folder.
