Hi,
I have Autocad Lt 2012 upgrade and I installed this on 3 computers about 3 months ago.
2 computers are working fine, but now when I try to open it on the 3rd computer it asks me to register it again.
When I do, it tells me that the serial number I have is incorrect.
This is very odd as it is still working on both the other 2 computers.
Can you help please?
Kind Regards,
Marcee
