Error - "Unable to Launch the Application" appears when I try to open Voyant

"Unable to launch the application" is a Java error (not an issue with Voyant itself) and it can have a variety of causes. Don't panic. It has nothing to do with your Voyant user account and in no way does it indicate that we have locked out your account or switched off your access to the software. The error indicates that Java is unable to launch the software. 

 

Cause: Normally, this error is due to a problem with your computer's cache of the software. Voyant uses Java Web Start to store (cache) the application locally and to send software updates to your computer automatically, as they become available.

First a question. 

When did you receive the "unable to launch application" error? 

a) When you clicked the desktop link to Voyant or the link in the Windows Start menu > All Programs? 

            

If you received the error when attempting to launch Voyant from your desktop shortcut, first try revisiting our website (being sure to visit the correct website, of course), sign in, and click the Plan Now button to reinstall the software. Clicking Plan Now should restore your cache of the software. Voyant can then be opened as usual, from the desktop shortcut.  Read more >> 

 

b) When you signed into the Voyant website and clicked the Adviser button

If the error occurs after clicking Plan Now, on the Voyant website, the software was unable to cache or re-cache the software. In that case, the error may have a number of different causes and it is best to look at the error message to know how to address the problem. Read more >>

Also, be sure never to re-title/rename the desktop link. Doing so can also interfere with the caching of software updates.
