Then I bet you have the wrong one. Your RSLinx Version 2.43 disk may have been issued before the Windows XP operating system was even a gleam in Bill Gates's eyes. You need the "1784-PKTX(D) Win2K XP Driver". Uninstall your old driver and download and install this one:I did use the driver that was on the rslinx disk.
