Thanks for posting your bug report, much appreciated.

Not sure if this will help but you can at least try it for now:
Go to Applications & find WireShare, Control (or Right) click & choose Get Info. Change the option from Run in 32-bit. If it's enabled then disable it or vice versa. See if this fixes the launching problem. (Here is a sample image using LW as an example.)

Another thing you could try is setting up a test account. This only takes a few minutes & can be easily deleted after use. See if WS opens ok in that account.

WireShare will default to using Java 6 if it exists, even if you have Java 7 installed. If Java 7 is the only java installed then it will use Java 7 or later.
