I have problem opening HDFViewer on win10.
I installed HDFView-3.1.2-win10_64-vs16.zip from this link: enter link description here,
Visual C++ Redistributable Packages from this link: enter link description here
and have added HDFViewer to environmental variables. "USERPATH\AppData\Local\HDF_Group\HDFView\runtime\bin"
" At the end, restarted windows; however, I still get the same error message which shows 1 seconds and disappears.

The error says what the problem is: The loader found 3 candidates for log output handlers. You need to find a way to remove 2 of them from the load path.

The .jar files with nop in the name are no-ops, that is, they are stubs that accept method calls to log output, but they do not cause any output. The file with simple in its name actually generates log output.

Any one of these files being present would fulfill the requirement for a logger endpoint. The loader does not know which to choose and so sits on its virtual hands and pouts.

  • Thank you for the help. I deleted the 1st and 3rd ones. The mentioned error was solved. But Now, this message appears and still no success to open the app. Isn't there any log I can see more detail on this cause it disappear so fast that I can hardly take snapshot: [main] INFO hdf.view.HDFView - Current directory is C:\Users\Simin [main] INFO hdf.view.HDFView - Menubar created – Simin Maleki Apr 16 '21 at 03:50

    I am glad to have helped you solve your problem. Please accept my answer and upvote it. You do not say what the new error is. Two further suggestions: 1) Look at the source code, especially the startup part. 2) Use a debugger to set a breakpoint, and step through the initialization. – Mike Slinn Apr 16 '21 at 03:59
