Foxflash Common Errors and Solutions
Problem 1: Got “Invalid Class” Error
This error invalid class may appear when running foxflash software and cannot enter the file.
It’s the operating system issue.
Better install software on a clean Win10 64-bit system.
If it is a Win10 64bit system, make sure the Windows Defender is off and the anti-virus program is off. Or try to reinstall the system.
Problem 2: Cannot find the SN of Foxflash ECU Programmer
Check the device serial number on the backside of the foxflash main unit.
The Serial number is your code to activate the device.
Don’t release that SN to anyone. It’s a safe code for you. Don’t let any third party or guys know that code or it is easy to let your tools lock.
Problem 3: Cannot Find DFB2XX.dll
The solutions are different for the different situations below.
Situation 1: run foxflash Manager and appear this error.
For 64bit system, Press “Install driver” to install driver.
For 32 bit system, the driver is not installed completely.
Go to FoxFlash/DFBTech_DRIVER/amd64 folder, copy and paste all files in this folder to C:/Windows/SysWOW64 folder
