The canfd configuration of freemaster

When configuring the can communication plugin, connection characters cannot be generated. Is there a new version of the can communication plugin for replacement?

Hello,

the error you show is a sign of wrong FreeMASTER installation. Please re-install the latest version (3.2.6) as administrator. If you already have the latest version installed, you can fix the plug-in registration by running the "register.bat" as administrator. The register.bat is typically located in installation folder c:\NXP\FreeMASTER 3.2\FreeMASTER.

The version 3.2.6 brings updated CAN communication plug-in, which also supports CAN-FD mode for some host interfaces (IXXAT, Kvaser and ZLG).

Regards,
Michal

When I downloaded the latest version (3.2.6), it showed that the installation was unsuccessful. However, when I installed the previous version again, the installation was successful。So I kept the new version of the plugin and put it in the old version, and the initial problem occurred

Hello,

let's try to solve the 3.2.6 installation issue. There are some typical issues when re-installing new versions described in this post.

Can you try to un-install the older version first, then clean/remove the C:\Program Files (x86)\Zero G Registry\.com.zerog.registry.xml file as discussed in that post?

After this, try to install 3.2.6 as administrator.

Thanks,
Michal

I have tried your method. If I don't delete that registration file, I won't be able to install it. Only after deleting it can I install it, but after installation, there will be a problem of unsuccessful installation. I'll try again after you say so. Thank you very much

I tried again following your method, and the result was the same. In addition, the installation problem is the same when using a computer that has not installed this software before. Do you have any other solutions. Besides, I want to know where I can see the installation logs. Thank you very much.

The installation log is displayed as follows

The error=5 typically means "Access is denied" - for some reason your system does not allow plug-in registration. Do you run your installer "as administrator" ?

As a experiment, please start command line prompt "as administrator", then 'cd' to "c:\NXP\FreeMASTER 3.2\FreeMASTER" and run register.bat.

Send a screenshot of the console output.

Thanks,
Michal

But I can't open freemaster, even though I'm running it as an administrator

Please try the experiment I suggested above:

Start "cmd" command line prompt "as administrator", then 'cd' to "c:\NXP\FreeMASTER 3.2\FreeMASTER" and run register.bat.

Send a screenshot of the console output.

It should look similar to mine:

Yes, the same as yours

Re: The canfd configuration of freemaster

MichalH — Thu, 27 Nov 2025 08:32:03 GMT

It is not the same - notice the error messages in your output.

Please run this command in the same console:

regsvr32 mcbobjps.dll

You shoud get a success message window. (but you will most likely get an error message):

Please share the output screenshot (You can use a pritnscreen key to get a screenshot to a clipboard and then Ctrl+V to message) .

What should I do next

Hello,

the error code 0x80070005 means Access Denied. I suspect you have not used the "Run as administrator" when running the cmd.

Locate the register.bat file in Windows Explorer and run it "as administrator".

Is there any other reason? I had a problem during the installation. At that time, I didn't need to run this file yet
