I tried it with two different Windows machines and changed the default for the timeout in knime.ini, still a time out. The progress always seems to stop at 49% of the 66MB .jar file.
yes, I have a virus scanner and changed the settings in knime.ini like this (which i googled):
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.readTimeout=10000
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.retryAttempts=100
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.closeTimeout=3000
-Dorg.eclipse.equinox.p2.transport.ecf.retry=15
-Dsun.net.client.defaultReadTimeout=30000
Still not working unfortunately. Other extensions (e.g. Source for Text Processing, Python Integration) worked totally fine, but I got the same problem with Text Processing - Deeplearning4J Integration.
