[flipsantos]

When i try to install autodac 2012, the installation wizard shows me this error.

I'm using OSX Mountain Lion.

Can anybody explain me what is going on?

Thanks

Please search "autocad" in spotlight to check if you have it already installed somewhere.

Thanks for helping me wei503, but the spotlight doesn't show me anything installed on my machine. I don'd know what to do now.

Could you please follow the steps below and let me know what is the output?

1. Open Terminal window > you can find it by typing terminal in spotlight

2. In Terminal window, input "find /Applications -name UPISpec"

Thanks,
