Specs: Windows 7
My husband is a Land Surveyor & uses his laptop with Auto-Cad and he's been told to get 32 bit as the 64 bit gets "confused" and doesn't work as well with Cad as a 32 bit. Your opinions please.

Autocad 32 bit doesn't work with 64 bit OS.
If he has 64 bit win 7 he should install 64 bit version of autocad. The same goes with 32 bit.
The beauty of 64 bit is, it can use more than 4gb of memory.

✔ Best Answer
hello

Just for information: 32 bit software should work on 64bit Windows due to the fact that 64 bit windows supports WoW (Windows on windows) which is a compatibility layer that allows it to run 32 bit apps. The 32 bit versions of windows have the same thing to allow it to run 16 bit apps ...

Anyway, to be on the safer side; If you husbands laptop is a 64bit, then it;s prefered to get 64bit Application as it uses its effeciency etc etc.

The 32 bit version of Auto-Cad is not compatible with a 64 bit OS. You must use the version appropriate for your OS. The 64 bit version will be the superior product. It may be possible to run the 32 bit Auto-Cad on a virtual machine running on 64 bit Windows but that is rarely a good solution for professional use.

Depends on the exact version he has.

All 32 bit software should work on a 64 bit OS. The problem may be that some part is not fully 32 bit.

As a professional he may need to purchase the 64 bit version if he uses large files.

Otherwise just get a 32 bit version of Windows.


There are many that report no problems with running the 32 bit version on 64 bit OS. Again it is the exact version he has that makes a difference.

AutoCAD 32bit does indeed run fine on 64bit Windows, you need to convert the installer application using the Longbow Converter software (www.longbowsoftware.com/Converter.php). I've been running it now for months with no problems at all.

He should run the 64bit because he can run a lot more memory than the 32bit can and that will improve his productivity when working with large files (32bit Windows is limited to 4GB but actually uses a bit under 3.5GB of memory, possibly less if the graphics does not have dedicated memory. A 64bit laptop should handle at least 8GB, probably 16GB and possibly 32GB of memory). More memory is definitely better with Autocad, Photoshop, and similar programs.

Those 32bit applications that use 16bit installers are old versions where people are trying to avoid purchasing a new version of Autocad and using the same version they have used since Windows 95. That is also why 'they' say that the 64bit version is confusing since they are stuck never having upgraded and have never bothered to learn any of the new features that are probably the same on all newer versions (32bit and 64bit) of the program. Newer is better and 64bit is better for those reasons.

You have to be a little bit crazy to keep you from going insane.
