Can anyone help? I've being trying to update my Laserworld software from the 2008 version to the 2009 version. I've downloaded it, but when I go to open the downloaded file I get the following error message:

C:\Users\24CARR~1\AppData\Roaming\MICROS~1\INSTAL~1\{CACBD~1\_5A2E1~1.EXE
The NTVDM CPU has encountered an illegal instruction.
CS:0000 IP:1204 OP:ff ff 00 00 98 Choose 'Close' to terminate the application.

I contacted Laserworld and they tell me it seems to be a problem with opening the .rar archive. I'm using my laptop which runs Vista 32 bit.
