1. If you own a version 3.x product, you can write to [email protected] and specify the email address used when placing the order.  In this email, you can request a new trial version of web messenger 3.x.

 

2. If you don't own a version 3.x product, you can't get a new trial version of web messenger 3.x. You should use the version 4.0.

 

3. Version 3.0 can not be installed with version 4.0 on the same location.  You need to choose version 3.0 or version 4.1.

 

4. If you want to upgrade version 4.1 and you own a version of 3.x, we do offer an upgrade discount.
