      Hello,

      I am having trouble with the student version of ANSYS 2021R2. When I try to open Fluent I get the Failed to validate connection error. I have read through and tried as many of the fixes as possible to no avail. The PDF attached shows everything I have tried so far.

      Thanks so much for any help!

      When I try to start ANSYS Fluent I get the following error. I am running Ansys2021R2 student.
      ┬ÀI have tried all of the following steps:
      ┬ÀUninstalling and reinstalling the software
      ┬ÀTurning off defender firewall
      ┬ÀTurning off Kaspersky firewall
      Changed edge to internet explorer
      ┬ÀChanged MPI type on start up
      ┬ÀOpen Fluent standalone using File Explorer
      Program opens then closes

      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.

      Hi Geo,
      Thanks for the quick reply.
      I tried looking in the System32 folder - and could not see any of the dynamic link library files you listed: See below.



      The full output of the "set" command is below.

      OK I just uninstalled 2021R2 and installed 2020R2 and now everything seems to be working correctly.
      Thanks!
