CAMEO: Downloading, Installing, and Running ALOHA

Downloading ALOHA version 5.4.2


 Note: The installed program includes an extensive on-screen help system (rather than a spearate manual). However, you can also download the ALOHA Examples (PDF) document (54 pp, 1.5 MB, About PDF) to see three step-by-step fictional examples.

System Requirements: The Windows version requires Windows XP, Windows Vista, or Windows 7.  The Macintosh version requires OS 10.5.8 or greater.

Installing ALOHA


If you have a previous version of ALOHA:

It is best to install the new ALOHA application in the same folder as your previous version. This will replace the old application with the new one, while still maintaining all of your settings. Any chemical information that you have added to the chemical library will not be saved and you will need to re-enter that information.

On a Windows PC

Once you have downloaded the installation program, double-click the ALOHA application file, then follow the directions you'll see on your screen. 

On a Macintosh

Once you have downloaded the installation program, the installation folder should open automatically. (If it doesn't open automatically, browse to the folder and open it.) Double-click on the ALOHA application installer icon.  Follow the directions you'll see on your screen. 

Starting ALOHA

On a Windows PC

To start ALOHA, open the Start menu, then point to Programs, and then click ALOHA.

On a Macintosh

Double-click on the ALOHA program icon inside the "ALOHA Folder" (which is inside the Applications folder or wherever you installed it).
