If you have an EBCAN purchased in the last two weeks which has a serial number on it then unplug the EBCAN when uploading. That will not be necessary after the next release which will update the EBCAN firmware.

Question: what issues did you capture with the 4.6.7 version? Is it something related with the "Improved CANFlex operation"? or with the Flashpro Firmware itself?

try update to 4.6.8，i cant upload tune to ECU with 4.6.7，fixed in .8

I just did, but the FP still doesn't comunícate with Manager app

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

I did that with both versions.

What is your serial number?

FP-2012SI-118115

I just notice that firmware version has been rolled back to 279 in the FlashproManager4.6.9, I will try tomorrow and see if it solve my issue and let you know.

Same result....

Your download link also isn't working for this version, and when I attempt to update Flashpro Manager from the software itself I'm on 4.6.6.0 on Windows 10, as soon as I click update it tries to launch `update.exe` like normal but I get:

Title: Unsupported 16-Bit Application
Message: The program or feature "\??\C:\Users\my_user\AppData\Local\Hondata\FlashPro\update.exe" cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

Somehow the device sometimes it seems is able to comunicate with Manager and in that I try to upload a file and shows the error in the image.... I think it is done.... what I see is the FW 279 caused a failure in a memory component inside the FP.
