      Trying to launch Fluent from Start results in this.

      @Millen_Samantaray Some other (non-ANSYS) software installation may put older version Intel Compiler dynamic link library (e.g. 2017) files under C:\Windows\system32, including:
      libchkp.dll
      libgfxoffload.dll
      libicaf.dll
      libifcoremd.dll
      libifcoremdd.dll
      libifcorert.dll
      libifcorertd.dll
      libifportmd.dll
      libioffload_host.dll
      libiomp5md.dll
      libiompstubs5md.dll
      libirngmd.dll
      libmmd.dll
      libmmdd.dll
      libmpx.dll
      liboffload.dll
      Rename C:\Windows\system32\libmdd.dll (e.g. to libmdd.dll.old) may resolve the issue.
      Also suggest rename (delete or move) other Intel Complier dynamic link library files in above list in C:\Windows\system32, and notify other (non-ANSYS) software vendor not to put such files in C:\Windows\system32, since different applications may need different versions Intel Complier dynamic link library.
      Please also send the full output of running the "set" command from a command prompt.

        Hello,

        I tried your method
        but I don't have the files you mentioned above in my folder.

        I am very anxious because it is about my master's thesis
