Hi,

I installed successfully Autocad 2009 also 2012 without any error report, then a tried to run program (.exe):

1) In Autocad 2009 - program loading then stops (Autocad is not responding)
2) In Autocad 2012 - program starts but before show main window of this program, fail (drop down) without any error message

- using last version in 64bit Win 7, Autocad- trial version

I do not know where could be a problem, does anybody help me?

Thank you in advance
