CAD Assistant can't write .mtl file

When using CAD Assistant to convert a STEP file to a OBJ file, the OBJ file is written, but then there is an error saying the .MTL file can't be written.

The colors are correctly displayed from the STEP file, so I know it has some material information.

Is there a trick to getting the .MTL file written?  I tried running it as the administrator and that didn't help.

Could you please describe the scenario in more details?
E.g. tested platform, STEP file / path used for saving OBJ file, error message (or screenshot), version of Open CASCADE CAD Assistant..,

The STEP file was exported using Alibre to version STEP 214.

CAD Assistant version 0.9 Windows

11:51 Model saved in OBJ format to file 'C:/.../Weather Station Mount.obj' in 0.0421045 s
11:51 File can not be written!
      C:/.../Weather Station Mount.mtl

I've attached the STEP file.

This can be unstable in CAD Assistant 0.9 due to bug - problem should not occur in next release (as tested in 1.0 BETA),

Could I try the BETA?

There is no public beta-testing for CAD Assistant yet.
But you may contact Open CASCADE support services, if this problem is urgent for you.
