Hi, I'm new to SAS and your forums. I recently installed SAS 3.9 on my main system (Athlon 2400, VIA chipset). When I try to update the program, the system tells me, "database definitions are up to date." However, when I check the site, I find newer definitions. Then, when I download the new files, it still shows the same Core and Trace Definitions. This is even more strange because I installed it on my laptop, and it immediately updated the files correctly. I thought it could be a bad installation so yesterday, I uninstalled SAS, Ran Registry Mechanic to clean any lingering vestiges from my registry and re-installed it. Today, my system showed: Definition Database Version: Core: 301 Trace: 1393 I tried to update the program, and got the message that there were no newer updates. When, I checked the site, I found: Core Definitions: 3402 02/13/2008 05:42PM PST 1946KB Trace Definitions: 1394 02/13/2008 05:42PM PST 125KB I extracted the definitions from the zipped file and copied them to the program folder. When I restarted the program, it still showed the previous values. TIA for any help or insight. --- Update -- I am able to update my laptop, but I still can't update my desktop machine.
