I have a problem when I still wants to work with a calcompdrawingboard III. The problem is that AutoCAD 2011 64 bit will not work with the WinTab ADI 4.2 driver. Win 7 recognize calcomps latest driver but AutoCAD will not. It´s working good on a 32 bit XP pro workstation. Can anyone help me with this.

Is it because it is a 16-bit driver?What version of Win7 are you using?  Home Premium?  Pro?  Ultimate?  Other?John Connor2011-02-02 12:12:42

Autocad11 is not properly work with win7 64 bit. I am also having lots of problem while using cad.

AutoCAD R11 might not work well with Win7 64-bit but RobWil is asking about AutoCAD 2011. This version is fully compatible with Windows 7 64-bit.
 
To RobWil: Make sure that also your hardware is compatible with Win7 64bit. Get the Win7 driver for your digitizer or try a general Windows driver (multi-vendor driver).

Please clarify what version of AutoCAD you are running for us.  Is it really Release 11 or 2011?
 
I could fully understand you having problems if you were running r11.  There should be no problems running 2011 on a Win7 64-bit system unless something was botched during the install process.
 
What kinds of problems are you having?  Please be as specific/detailed as you can.  The more information we have the better your chances of getting an answer.

I am using autocad 2011 version. Problem is now resolved. the problem with the installing process. I need to reinstall it and got it resolved.
