Troubleshooting#

On Windows computers, if Simplicity Studio 6 hangs on the splash screen, it is often due to company network man-in-the-middle (MITM) security certificate inspection. In this case, Simplicity Studio 6 must be adjusted to work with this network configuration.

Exit Simplicity Studio and wait approximately 10 seconds to ensure that the sts_back_end.exe process has stopped. Then, open the sts_back_end.ini file in a text editor. This file is located in the Simplicity Studio installation directory:

C:\Users\USERNAME.silabs\slt\installs\archive\v6-base-v6.1.0-171\SimplicityStudio-6\sts_back_end

Add the following lines to the end of the file, then save it:

-Djavax.net.ssl.trustStore=NUL
-Djavax.net.ssl.trustStoreType=Windows-ROOT

After saving the file, restart Simplicity Studio 6 and verify that it starts correctly.
