Following are the System Requirements for the MrSID viewer, created by LizardTech.com. Compatible Operating Systems: Microsoft Windows 95 Microsoft Windows 98 Microsoft Windows 2000 Macintosh Operating System 9.x Compatible Processors: 200 MHz PC processor (or faster) Apple G3 or later Compatible Internet Browsers: Microsoft Internet Explorer 5.0 or higher Netscape Navigator 4.7x At this time the MrSID viewer will not function with the Netscape 6 or 7 Internet browsers. It is also not fully tested and supported for Windows Millennium (ME) or XP. Macintosh OS X or those lower than 9.0 will also be incompatible with this viewer. While MrSID may function with these settings, if you experience errors there are no current fixes available. Thank you for your patience. You will still be able to fully access the Census Images Online using the HTML Viewer. We are currently working on other viewing options in an effort to improve our services. Please note that the MrSID plug-in viewer was created by LizardTech.com and is offered only as an additional viewing option for the 1790-1920 census images. Ancestry.com cannot guarantee that the MrSID viewer will properly function with your specific Internet browser and/or operating system. You should always be able to fully access the Census Images Online using the HTML Viewer that was created by Ancestry.com to be compatible with all systems. To switch from the MrSID viewer to the HTML viewer simply click on the "View This Image With The HTML Viewer" link that is located below any census image. On the later Census Years, e.g. 1930, download the Advanced Image. It will work fine. Janet
