Many thanks for the prompt answer.
I have followed your instructions and successfully installed
second instance of SSv4 , intended for BLE webinar during May.
By default if the installer is run again a new instance of Simplicity Studio will be installed. The default installation directory will have '_2' appended to it. The trick is that each installation should use it's own workspace, so the existing installation should be changed to use a different workspace than the default one before doing the second installation. Use the [File] > [Switch Workspace] > [Other...] command to create and switch to the new workspace. Simplicity Studio will restart using the new workspace. You can name the workspaces based on the intended use of each instance of Simplicity Studio.
A few years we have been using successfully a DEBUGADPTR1-USB (USB debug Adapter from SILABS) with our own designed Boards, Simplicity Studio v4, under Windows 7
Target was , usually C8051F380.
Now, after installing latest Simplicity Studio v4 to my new PC with Windows10 and new INTEL i9-9400 CPU, installation of SS v4 looks OK, but,
with same USB debug Adapter, I CAN NOT start DEBUG session with message :
"Adapter IF Invalid Parameter e.g. the serial number may be wrong "
I have older Version of C8051F120DK dev. Kit with Serial Adapter EC2... question is : can I use this EC2 serial Adapter to work/debug newer Silabs MCUs such as C8051F996-C-GU and/or C8051F920-GQ mounted on my own target Board ... using just two signals/wires (C2D and C2CK) from JTAG/DEBUG cable/connector ?
