Do you have issue with preview using QR code? Is your QR code not giving preview ? No mobile preview using QR code ?

Hey, if you have problem getting “Live preview on Devices” using QR code, Kindly understand this.

Many face problem that their QR got generated and is scanned and even read by mobile BUT no preview!! The reason is explained below.

When you create “Live preview on devices”, the output is created(generated) in your local PC only. Your setup may be such that your mobile can no-way connect to your local PC even thought both (your mobile device as well as PC with captivate) are having internet connection working.

Because your PC is having ip address something like “192.168.1.XYZ” or “192.168.0.xyz” or similar. These address are for intranet, means for local network and can not be accessed directly from internet. Same story is with your mobile. So your mobile can not access your PC output through internet(even though both are having internet connection.)

These both can talk to each other only if they are on the same network (to be exactly: on same local area network).

Consequently, if you want your mobile should show preview by reading QR code, then both should be accessing same router and there by they come on same LAN.

Note: Captivate does give clear message that both PC and mobile device should be on the same intranet, but often we ignore what software says or many could not interpret this message properly.

Reading seems to be so difficult these days. I was glad that Captivate offered such a ‘clear message’ as you write nicely.  Some terms seem very difficult for a lot of people, probably because setup of intranet is done by the IT-people. Not so lucky myself, have to set up everything myself, but that can be an advantage.
