I installed Trueview 2013 64 bit on a Dell M6600 laptop. It installs, but when run it says ac1st18.dll missing. UAC and antivirus were off. Tried uninstall/install again and repair, same problem. Copied ac1st18.dll from AutoCAD 2012 folder but then it was missing another dll. Copied that, then it gave another message about something else missing.
Trueview 2012 works fine.
