Upgrade to TMM 4.0.3 from 3.1.10 - A JNI Error has occured
#1
Hello,

I just upgraded my TMM 3.1.10 to TMM 4.0.3 through the upgrade button on the top right hand corner on a Windows 10 2004 64 with latest Java update (Java 8 Update 261)
I am now getting a Java Virtual Machine Launcher error: a JNI error has occured, please check your installation and try again. A java Exception has occured.
Running tmm.jar generates this error.
Here are some logs below, any idea?

Thank you very much in advance.

The old updater tries to start tmm with your installed Java version (which may be too low)

Does running the tinymediamanager.exe also throw this error?

Thank you for your reply. Yes it did.
I fixed the issue.
I reinstalled the 64 bit version of Java 8 Update 261 and overwrotte the update done automatically by TMM by a fresh 4.0.3 zip file content. It fixed the problem. 
Thanks again.

Hi @mlaggner 

I have the same issue after i updated to V4 and the error message is coming when i run the tinymediamanager.exe and all the other .exe files now but the workaround from Letloose worked for me as well
