Re: Could not connect to host localhost on port 21212

Hi Sanel,

The default port of the installer is 21212. So please check if another GUI installer (Process) is running in the background (Hint: Task Manager->Choose the option "Show Processes from all users").

If the process is running, then, you will have to end the process and restart the installation.

Or else navigate to the directory where the installer executable is present from the command prompt,

And use the following command –

sapinstgui.exe -port <port_number_other than 21212>

You can use something like this -

sapinstgui.exe -port 21213

Now you should be able to start the installation.

Cheers!
