Hello,
There are no specific settings in Lansweeper itself, or its configuration that are browser specific. As it seems to run fine in IE, we assume the application is working and operational.
To open it in Chrome or any other browsers, make sure you are using the same url as in IE. If the application would be using an SSL certificate, make sure also that the same certificate is enabled in Chrome also.
Make sure also to have the most recent version of Chrome installed.
