I am installing acad 2012 and have run into a potential problem. When I start up 2012 I get a quick error box stating "Heidi driver cannot be loaded. Switching to default software driver." From what I understand this has to do with a print driver? My question is how do I fix this, where can I isolate the driver that is causing the error message and either replace it or fix it? I have installed 2012 on other machines and have not had any problems. Also, I am able to use the program on the machine where this is occuring however everytime I start up I recieve the error message. Can somebody point me in the right direction?
