Hello Luiz,

 

Have you ensured that you computer has 64-bit OS and that you have downloaded and installed Java JDK for 64-bit? The launched GUI installer should also match with the OS and Java versions.

Regarding last MED-EKG projects, they are included on the ZIP file of application note AN4323, at the followinglink:

http://www.freescale.com/files/analog/doc/app_note/AN4323SW.zip

 

Hope this information will be useful for you.

Best regards!

/Carlos

Hello Luiz,

 

Have you installed the Java JDK that corresponds to your operating system before installing the Medical GUI? Detailed steps for proper installation of the Medical GUI on 32 and 64 bits systems are included on the Readme.pdf document that comes with the installer on the same ZIP file. (I have attached this document to this post).

 

If you have installed the Medical GUI without having Java, please uninstall the Medical GUI, then, install the proper Java version, and then, install again the Medical GUI.

 

Hope this information will be useful for you.

Best regards!

/Carlos
