Yes on the second computer it doesn't see the licence key.
I even installed the 4.8 version from the cd that I had since 2009 and when it updated to the new 7.0.147 version it doesn't see the licence it just tells me that it will expire in 29 days and i don't have a licence file to insert that's when I contacted iyogi on the 0800 number, they emailed me the file i have tried to insert it and I get an error message: unable to insert the licence key. the licence file does not contain any valid licence.
the agents from iyogi were of absolutely no help whatsoever. their solutions were uninstall reinstall, which I did didn't work or install avast free and then insert key again doesn't work. they got access to my computer and done the same things and didn't come up with any solution.
I even tried to update the 4.8 to 6.0 and it says it can't as I don't have the 4.0 version installed.
On my other computer avast updated by itself and I have the new version and if I go under maintenance - subscription it shows the correct details, date of purchase, date of expiry etc.
