This second question is not related to the first one. At the beginning, you reported a problem with the ctlscript.sh file in Azure but now you are asking about the WAMP stack (only available for Windows). Could you please let us know the Bitnami stack and the platform you are using?
If you want to install WAMP, you can uninstall the one you have in your machine right now and download the latest version from here
Once you have the file, run it to install the WAMP solution in your computer.
