Can we run AutoCAD 2010 32-bit AND AutoCAD 2010 64-bit on the same machine?

[JordanMrazek]

the purpose for this is because we use a piece of software with AutoCAD that will only work with the 32-bit version, and we only need it's features from time to time, but the bulk of our drawing must be done in the 64-bit version. Is there a way to install both versions on the same machine?

if not, can we install AutoCAD 2010 64-bit, and AutoCAD 2011 32-bit on the same machine?

no you can't

there is no way to run the 32 bit autocad on a 64 bit os without some sort of hack to the installation

[TravisNave]

Exactly.  The only other work-around that some people are using is to install a Virtual Machine on the 64-bit to run a separate installation of Windows XP 32 on the same machine at the same time.

if you have windows 7 pro higher it comes with xp mode which runs xp pro sp3 in a virtual enviroment

We already were able to install AutoCAD 2010 32-bit on a windows 7 64-bit machine. what I wanted to know was can we run BOTH versions of AutoCAD; 32-bit and 64-bit.

I like the idea of the virutal machine, I will look into that.

how can i run Autocad 2010 32-bit on os 64-bit  win7

[JordanMrazek]

We had no problems installing teh 32-bit version of AutoCAD 2010 on windows 7 64-bit,

and FYI everyone, the best solution we came up with for running BOTH autocad 32-bit and 64-bit on a windows 7 machine was to download and install Sun Virtualbox and install it on Windows 7 and then create a virtual instance of windows XP that we can run while in Windows 7, this way our user has simultaneous access to both the 64-bit and 32-bit versions.

Microsoft already offers a free version of Windows XP via Virtual PC for Windows 7 users.  Get it here:
