ARC just flagged a new version as available but the date appears to be wrong on it.
EZ-Builder Version 2013.09.01.00 [Download] [Release Notes] [Manual]
- Requires Microsoft Windows 7 or Windows 8
The version I have currently installed is 2013.09.04
It won't install because a newer version is already installed.
Ignore the "update", it looks like it is not an update (there is always a forum post about updates) but something on the cloud going a little funny or has been recovered.
If you have 2013.09.04 you have the latest version and there is no need to update.
