I have upgraded to Windows 7 64-bit and installed 3DWS 5.37 Builder Edition I obtained from TGC, and then updated to 5.52 via download from the automatic update, but the Save, Save As, and Export are all greyed out and unavailable in both editions on my OS. I turned off the user account control and re-installed as before using compatibility with Windows XP service Pack 2 on both the setup and executable, to no avail. I have a Dell Inspiron laptop with Dual Core AMD Turion 2.2Ghz and ATI mobility Radeon 4350 HD with 512MB dedicated RAM. System has 4GB RAM. Windows has all recent updates installed. My one concern is the graphics driver I am using is preinstalled, the only other one available from ATI is for Windows 7 beta only, though this should have no bearing on my issue anyway. Any thoughts would be appreciated. Thanks!
