  Hello,
  Attempting an installation of Ansys 2023 R1 on CentOS 7 and we are receiving the following error:
  qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
  This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
  Any suggestions are appreciated. Thank you.

  On my CentOS 7 installation the packages xcb-util-wm xcb-util-renderutil were missing.
  
  To diagnose such Problems in general set
  export QT_DEBUG_PLUGINS=1
  before starting the INSTALL script.
  In my case i got
  Cannot load library /tmp/ans_install_tmp20326/platforms/libqxcb.so: (libxcb-icccm.so.4: cannot open shared object file: No such file or directory)
  QLibraryPrivate::loadPlugin failed on "/tmp/ans_install_tmp20326/platforms/libqxcb.so" : "Cannot load library /tmp/ans_install_tmp20326/platforms/libqxcb.so: (libxcb-icccm.so.4: cannot open shared object file: No such file or directory)"
  The missing libxcb-icccm.so.4 is part of the xcb-util-wm Package.
