I am using ANSYS under my University license. I have done the nonlinear static analysis of a beam. I used to extract the tangent stiffness matrix using hbmat command. But now that the new version of ANSYS 2021 R2 is installed on my computer, by applying the same APDL Code, I receive the error " The HBMAT command does not support distributed FULL files". Later on, I noticed that in product launcher, distributed computing is selected in High performance computing setup. But after deselecting it and launching the program again and running the analysis, I receive the same error. 

Any help is very appreciated.

Can you verify in the solver output ( just a few lines down from the beginning as shown below , whether distributed computing is still being used? Also delete all the files (file.*) in the directory before resolving.

Dear Chandra, 
Thank you for your response.  

As you mentioned when I activate "use distributed computing" in "high-performance computing setup" of the product launcher, it can be validated in output as below

  *****  ANSYS COMMAND LINE ARGUMENTS  *****
  INITIAL JOBNAME              = Timoshenko_nonlin_transient

  GRAPHICS DEVICE REQUESTED    = win32   
  GRAPHICAL ENTRY              = YES   
  LANGUAGE                     = en-us               

And when it is not activated, it also can be seen in the output but there is still the same problem.
