Have you got the following versions running (check in the Help->About wiondow)
Scanner: V7.5.4 build 64
v7obdii.dll: V7.5.4 build 64
Tuner: V7.5.4 build 64
FlashScan firmware: V2.05.18 (Check using FlashSCan options: F4->F3->F1 then scroll down.
If you are running all those versions, can you (after the link fails),
first: save a trace file in FlashScan.
second: generate an error report in the Scan Tool software.
Send both files to me at
[email protected] with a link to this thread so I can correlate the two.
Regards
Paul
