I have KNIME AP 5.2.0 on Windows 10. I installed it from the downloaded .zip file a few weeks ago. Today I downloaded : org.knime.update.analytics-platform_5.2.1.zip com.knime.update.partner_5.2.0.zip TrustedCommunityContributions_5.1_202401170807.zip I added them to the Available Software Sites, and enabled just on item: [image] and then went to install an extension from it as normal. I went to File > “Install KNIME Extensions…” … and no dialog window opened (which I would expect). I got no response at all. AP didn’t hang. No windows opened, no error messages, nothing on the status bar. It was as though I had never clicked on that File menu option. If I go back to Available Software Sites and disable org.knime.update.analytics-platform_5.2.1.zip, I am then able to open a dialog using File > “Install KNIME Extensions…” (albeit with nothing available of course). I’ve tried restarting. I’ve tried re-adding the zip. Bottom line - if ANY local zip file is selected, then KNIME AP doesn’t open the dialog. If a local zip file AND a web URL are selected, then I try to “Install KNIME Extensions…”, it will open a dialog as follows: [image] No mention of a failure of the local zip file. There’s a failure to read the https repository because those sites are somehow blocked by our corp firewall (hence the need to download a local zip). I had a colleague try on her machine with a new installation of KNIME 5.2.0 and she had the same problem. She opened a workflow that had an Excel Reader node, and it failed to even load that node (it looked as if it had been deleted - there wasn’t even a node there with a red hash mark). When she disabled the local zip in available software sites then she was then able to open the same workflow and Excel Reader loaded properly. Any suggestions?

And another friendly hello :slight_smile: PKIX path building failed does indeed suggest a networking / SSL issue. However, should you be only working with offline update archives, please note that there is a bug in KNIME 5.2.0. A workaround is here: [image] Downloading Extensions by Adding Local Update Sites - Unhandled event loop exception KNIME Analytics Platform Hi @arushib30 , We can confirm that offline update archives do not work in KNIME 5.2.0. We are planning on providing a resolution in KNIME 5.2.1 (internal bug reference: AP-21958). 5.2.1 is scheduled for release within this month. We’re very sorry for the inconvenience. Kind regards Marvin Apologies for any inconveniences. Kind regards Marvin

Hi @ajackson,

I found the following in the forum regarding the PKIX path building failed issue, does that help you already?

Best regards
