ArchiCAD Tip: 64bit-only OS Support

In relation to the new release of ArchiCAD 17 (expected during the summer of 2013), there is some very important information regarding Windows 32-bit and 64-bit Operating System (OS) support, of which every ArchiCAD user needs to be aware.
Mac users don't have as much to worry about this, as only OSX 10.7 (Lion) and OSX 10.8 (Mountain Lion) are supported - this eliminates a lot of complications.

Please be aware, this may get a bit technical for some... so breathe deeply and regularly!!

When ArchiCAD 17 Full & Solo versions are released, only 64-bit versions of Windows Operating Systems will be supported, and ArchiCAD 17 can only be installed on these Operation Systems versions.

This list includes:
• Windows 8 64-bit
• Window 7 64-bit
• Mac OSX 10.7, 10.8

This list EXCLUDES:
• Windows 8 32-bit
• Windows 7 32-bit
• Windows Vista 32-bit
• Windows XP 32-bit
• Windows XP 64-bit

Windows Vista 64-bit will be capable of running ArchiCAD 17, but is not supported by Graphisoft, thus (in turn) not supported by Dedicated CAD Systems.
It is very important that you check what Operating System(s) are running on computers in your office, so that there are no potential complications when ArchiCAD 17 is released.

How to check if your current Windows OS is 32-bit or 64-bit?
If your keyboard has a <Pause> or <Pause | Break> key, then press once the <Windows> + <Pause | Break> keys at the same time (the Windows key is typically a flag icon to the left of the <Spacebar>)
- or -
Goto Start > Control Panel ( > System and Security) > System

On the dialog that is displayed:
• if the term '64-bit' is EXPLICITLY listed, then the OS is 64-bit
• if the term '64-bit' is NOT EXPLICITLY listed, then the OS is 32-bit

Only Windows 7 64-bit and Windows 8 64-bit are valid for ArchiCAD 17.

What to do if you are running a 32-bit Operating System:
If your system is 32-bit, you will need to find out if your hardware is capable to run a 64-bit OS.
It is possible that your 32-bit operating System was installed on a '64-bit capable' computer.

How can I find out if my computer hardware is ready for 64-bit?
• Goto the Start Menu
• Click on Run, or type Run in the Start Menu search entry (see below)

• In the Run line, type msinfo32.exe
• Click OK
The System Information page appears and you will find a 64-bit capable computer listed as 'x64-based PC' under 'System Type'.

If you have a 64-bit PC with a 64-bit OS, you don't have to change anything!!!

If you have a 32-bit capable PC running a 32-bit Operating System, you will need to swap to, (or buy) a different 64-bit capable PC running either Windows 7 64bit or Windows 8 64-bit.

If you have a 64-bit capable PC running a 32-bit Operating System, and the Operating System is Windows XP or Windows Vista: you will need to buy an upgrade to Windows 7 64-bit, or Windows 8 64-bit.

If you have a 64-bit capable PC running a 32-bit Operating System, and the Operating System is Windows 7 32-bit or Windows 8 32-bit, you will need to:
• check that you have your Windows serial numbers / keys, and
• ensure you have your OS installation DVDs,
(or check with your PC supplier that you able to reinstall 64bit OS from an existing partition)
This will be a full OS reinstall >> that means first deactivating any software licenses on your PC, then backing up ALL your data beforehand, then reinstalling the OS and reinstalling all applications, and finally restoring your data
This full reinstall process is a reasonably large task, it might be a good idea to consult your IT staff about this.

The majority of the information above was taken from the ArchiCADWiki page Discontinued32BitSupport, including the two images, but some workflows have been modified and re-phrased by DCS.
