New subscriber to Avast Pro.
The purchased licence says that this product is licenced for THREE computers. I have installed it on my primary and secondary machine. Everything is fine on the primary machine but when the secondary machine is booted up, a splash screen comes up indicating this is a TRIAL installation and running out of time. I cannot find any method of correcting this. Any help. please?

Have you inserted the license file ?..you must do that on every install
Thank you. Only on the primary machine - no dialogue box for the licence was offered on the secondary install. Does this require a further install and, if so, are there any problems I should be aware of, please?

On the second computer Please go to Maintainance, choose Subscription and Insert License File
That should solve the problem. 
Thank you - will try that.

Just to update …
Because the installation on the secondary machine is a TRIAL version, there is NO maintenance function so the previous suggestion didn’t work 
What DID work,eventually, was to copy the licence file to the secondary machine, THEN go through the INITIAL sequence of PURCHASING a second copy and, once the setup eng had completed, activate the licence file. This APPEARS to have worked but I wouldn’t class it as the most straightforward installation routine!!! >:( >:(
Sorry I couldn’t help and am glad to see you got it working. There must have been a glitch somewhere in the process.
How about just copying the license file to the target machine (or transferring it on a flash drive, for example), and clicking on it in Explorer?
Thank you, Igor. Yes, the flash drive was how it was done but I would have expected something simpler. :-\
