Hi there,

I also run Win 7 and KNIME 3.7.2 and see both Utility and XLS Formatter. Did you update anything recently? I guess you tried to uninstall it and install it again?

Hi,

tried to reproduce it by updating KNIME but couldn’t. Also tried uninstalling and then installing and also nothing. Did you try with -clean option in your .ini file?

What -clean will do?

Hi @izaychik63,

The -clean option forces KNIME AP to recreate it’s plugin configuration files. Sometimes things go wrong during installation etc, this has been proven to fix some of these issues. Remember to remove this option again, as it slows down the startup time of KNIME AP.

best,
Gabriel

After restart with -clean still see just one Continental node. Should I reinstall again?
Also, I have warning and error below

Hi @izaychik63 ,

you did only restart? Try closing KNIME and then starting it again: Missing value on Linux

this is second time I’ve seen FrameworkEvent error for this module (com.continental.knime.xlsformatter)

This started after update, right?

Anyways will explore it and get back to you.

That’s an interesting stack trace as it has to do with rendering annotations on the workflow canvas, so i’m not sure how that could impact seeing the existence of the nodes in the repository. If you close all open workflows, you should at least no longer see this exception and it will rule out whether it is somehow impacting the populating of the repository.

Hi @izaychik63,

Just to check where this the steps you performed?

  • uninstall Continental extension
  • close KNIME and start it with -clean option
  • install Continental Extension

If not try it in that order. If you already tried it I will look further.

Ivan

Can you please try with a fresh installation of KNIME AP and a new Workspace? Just download the zip and extract it someplace.

It will be a hard choice. I do not have installation permissions anymore.

You do not need any special permissions to run use the version shipped with the zip file. You can just extract it and double-click the knime.exe file.
