JNI Error On Manual Install on Win32

I attempted to upgrade (Manual install) the latest version traccar-other-4.13.zip on a Win7-32 computer.
I am receiving the following error. . .

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/traccar/Main 
has been compiled by a more recent version of the Java Runtime (class file 
version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I have upgraded Java to the latest version: Version 8 Update 291 (build 1.8.0_291-b10).
I have reverted to my backup of the previous manual install.

You need Java 11 or newer.

I have located OpenJDK 16 at https://adoptopenjdk.net/ which appears to be the latest version.
Will this be suitable?

I would install version 11 instead because it's LTS, but version 16 should work as well.

Why not Oracle version? It's more common.

https://www.oracle.com/java/technologies/javase-downloads.html

Doesn't look like it will be compatible with Win7 as it requries 2012R2 or later. I'll keep looking.

Sorry Anton, our post crossed. I am following your link for the Oracle version.

The oracle version is for X64. I need one for Win7-X86.

Then maybe adoptopenjdk is your best bet.

I am going to give it a go and see how it goes.
From reading, Oracle went to only X64 architecture as of Version 9.

I will report back on my results. It will be another 4 hours before I can try again.

Well I have installed Java 11 from adoptopenjdk and then executed the old version of traccar and it worked. Great Start.

I then test ran the latest version of traccar (traccar-other-4.13.zip) and it actually executed this time but it then crashed.
The log file is showing the following. . .

Any ideas? Meanwhile I will revert to the old version of traccar.

Looks like some database migration issue. What version did you have previously?

I wish there was an easy way to identify the version that was running.
From looking in the database and in the schema folder it appears to be 4.1

Try removing position_deviceid_fixtime index from changelog files.

I removed position_deviceid_fixtime index from changelog-4.7.xml and traccar successfully started.

It is now running the latest version of traccar.

Many thanks Anton, your support is brilliant as always.
