Hi

Can you provide the environment and product information? You can find these information in the log file which is located in <studio installation directory>/workpsace/.metadata/.

for example:

Hi

Pleaser refer to the installation guide, Java 17 is not a supported Java version for v8.0.1, please install Java 11.

BTW, don't install studio into a long path that contains special character such as blank space.

I see, thank you for that info I will try this. Do I have to deinstall the Java 17 version for this or does talend automatically uses Java 11 if it is intalled on my pc?

[Anonymous · Accepted solution]

You can have multiple Java version installations on the same machine if you don't want to remove Java 17 from your machine, then specify a JVM to launch studio, please refer to this KB article.

Thank you shong!

Hallo,

I have a quick related question: To execute an executable which was done by talend v8 on a different PC, does this PC also have to have exactly Java 11 installed? There doesnt have to be talend installed right? Thank you!

[Anonymous]

@Not defined Not defined​  Yes, you are right. The executable file can be executed directly or scheduled with third-part scheduler.

[Moro]

Thank you shong. Does the third party have to have a java environment installed and does the version matter?
