Hi,
We have installed Autocad Architecture 2008 on 64bit Windows 7. The
error we get is when sometimes trying to generate a rendering. The
message is: Description:  A problem caused this program to stop interacting with Windows.Problem signature:  Problem Event Name:    AppHangB1  Application Name:    acad.exe  Application Version:    23.1.51.0  Application Timestamp:    45cffe3b  Hang Signature:    ab3b  Hang Type:    256  OS Version:    6.1.7600.2.0.0.256.48  Locale ID:    2057  Additional Hang Signature 1:    ab3bc8137bbb5395171efaa0d1110d68  Additional Hang Signature 2:    24b2  Additional Hang Signature 3:    24b2d88f483a82f8ac6e6d3bec8cdd0c  Additional Hang Signature 4:    ab3b  Additional Hang Signature 5:    ab3bc8137bbb5395171efaa0d1110d68  Additional Hang Signature 6:    24b2  Additional Hang Signature 7:    24b2d88f483a82f8ac6e6d3bec8cdd0cRead our privacy statement online:  http://go.microsoft.com/fwlink/?linkid=104288&clcid=0x0409If the online privacy statement is not available, please read our privacy statement offline:  C:\Windows\system32\en-US\erofflps.txtAUTO CAD stucks and nothing can be saved... please help!!!!!!!!

What are your full computer specs?Are you trying to render very large, complex scenes when Autocad gets stuck?You might want to consider upgrading to Autocad Architecture 2011. 2008 is not fully compatible and is not supported on Windows 7.
