i use autocad 2013 until yesterday when my windows8 upgraded to windows8.1, now my autocad does open it asks me to repair the license and to get a valid serial key. (it was free three year student version)
i need help...
You probably should not post your serial number and other date found on "2.jpg".
"still need help" din work for me...
i have a new problem now... i tried downloading autocad 2014 and autocad 2015 on windows 8.1 but both didn't install... its gives a "communication error", what do i do???i need help!
Hi,
do not start the install from internet, first download the application with "browser download"-option and from that downloaded file start the installation with admin permissions and disabled antivirus.
