Frequently Asked Questions


[Q] Is CAD International developing newer versions of DRCAuto compatible natively with Windows 7, both 32bit and 64bit machines and with current versions of AutoCAD®?

[A] Since obtaining the I.P. of DRCAuto software a year ago we have been working tirelessly to release an updated product fully compatible with both Windows 7, 32bit (x86) and 64bit(x64) and current releases of AutoCAD®. Unforeseen delays have hampered these updates.

[Q] What can I do until then? Is it possible to run current DRCAuto software on Windows 7 (both 32 and 64 bit machines)?

[A] The answer is yes. For Windows 7 32 and 64-bit platforms, the solution is to install both AutoCAD® and DRCAuto under what is known Windows XP Mode.
