I use version 4.7.8
Error identification:
In the error images, the system requests installation, but presents an error.
When trying to run the installation, I receive the message that it is already installed
I don’t know what else to do
I tried to use Node here on the site, but an error also occurs.
on the following screen, the finish option cannot be selected. The system is unable to perform the installation
Hi @geviholan ,
Welcome to the KNIME forum.
What was the origin of the workflow that you are trying to use, and which version of KNIME was it created with?
If you respond “No” to installing the “required extension” what happens?
Using the “Help - About…” menu
and then clicking Installation Details, does it show the KNIME Expressions installation?
(You can, if you wish, uninstall that extension from this screen by selecting it and then using the uninstall button. Then try reinstalling it again. It may fix something, but difficult to say at the moment what the actual problem is)
Hi, it worked, I did it! thank you for the help!
With your support through the “help” tab, I was able to install it.
