CF2021 Enterprise updates not downloading

Hi, I am running windows server 2016 with licensed version of CF2018 Enterprise and I just installed licensed version of CF2021 Enterprise. When I go into cfadmin on CF2018 and click to download the latest update (update 16) it downloads without issue. When I go into cfadmin on CF2021 and click to down load any of the available updates 3 thru 6 it just sits there and says downloading but nothing is happening. Any explanation why that works on CF2018 and not CF2021 on the same server? Thanks.

Yes, this is a common problem, and it has to do with the jvm cf is running. Further, my guess is that your cf2021 is running with its original JVM (11.0.1, from 2020), while your cf2018 may be running with a JVM  (8 or 11) that’s been updated since then. Can you confirm the jvm reported on the settings summary page of cf2018, and for 2021?

As for updating the jvm for your cf2021, the current latest update to 11 is 11.0.18. But beware that updating beyond 11.0.17 has an issue, as does updating beyond 11.0.11. I discuss both those issues in my blog posts announcing recent jvm updates, and I also discuss there the process of updating the Java used by cf, as well as resources for more help. See, for example:

New updates released for Java 8, 11, 17, and 19 as of Jan 17 2023 https://www.carehart.org/blog/2023/1/17/java_updates_Jan_2023

I also discuss in that one a unique new challenge in the 11.0.18 jvm installer (for Windows, Linux, and Mac), which won’t hit those who use the jvm zip extraction approach instead.

Finally, as I note there, if you “just want it done”, I could help you via remote screenshare consulting in less than 15 mins.  I share all the info to help those who want to better understand things, but I appreciate some have “better things to do with their time”.

Hope that’s helpful.
