Informix

Malcome:

Yes, I ran into the same issue. I upgraded from Java 11 to Java 21 (well I actually had v17 & v21 already installed, I just changed the path so that the installer saw the v21 Java) and was able to install. It's ikely that any release after v11 would work (I know that the readmes state that you need Java 8 or later, but there's something in the Java 11 that the installer does not like.

The error still appeared after installing openJDK-21. However, it was installed under my Windows home directory, under .jdks folder. I moved jdk files to another location and the error did not appear. However, the installer just terminated without installing anything. The good news is that Art's solution fixed a similar issue when installing Informix server on Ubuntu.

UPDATE: The Windows installer ran after changing the command to ids_install -i gui. However, a new error appeared:

That latest error looks like you're trying a domain installation which would try and create the user informix (and others) as domain users (and require privileges and permissions accordingly).  You'd need this if the database server later had to authenticate domain users with any applications connecting to it.

If you don't need this, e.g. if you want to have Informix running on your personal device, you could still do a local installation instead.

Hi Malcom,

A Java LTS runtime is required for the installer. The latest Java LTS version is 25 and that worked for me.
