We have a copy of Hawths tools that only work in ArcGIS 9.3, so I would like to keep it on my computer. However, most of the work we do in our lab is done with ArcGIS 10.

Therefore, would it be OK to install both ArcGIS 9 and 10 on the same computer? If so, can you give and tips/experience on how to best achieve that?

It can if you have a Virtual Machine Installed - We run Windows 7 (ArcGIS10) and a Windows XP VM (ArcGIS 9.3) Virtual Machine - – Mapperz Jan 10 '12 at 15:05
@Mapperz good point, thanks! – hpy Jan 11 '12 at 0:03

The help file says:

Can ArcGIS 10 be installed on the same machine as ArcGIS 9.3.1?

No. For users who want to install ArcGIS 10 and ArcGIS 9.3.1 on the same machine, Esri recommends using a virtualization tool (such as VM Ware's VM Workstation or Microsoft's Virtual PC) and install the new instance of ArcGIS on that virtual machine.

We had initially announced that we would be able to support running ArcGIS 10 and ArcGIS 9.3.1 on the same machine. However, we were not able to accomplish this for ArcGIS 10.

(FWIW, I'm successfully running Hawth's Tools in ArcMap 10. Although it's not listed as being supported at this version, it seems to work.)

+1 BTW, looks like Hyper-V will be part of Windows 8 client. – Kirk Kuykendall Jan 10 '12 at 3:12
Thanks so much, and for letting me know that Hawth's Tools work in your case. – hpy Jan 11 '12 at 0:04
I just tried installing Hawth's Tools in ArcMap 10.1 and this also seems to have worked. – Stephen Lead Oct 6 '12 at 4:59
