With fresh install, ble_app_template_s110 fails to load

[Bret Foreman]

After a fresh install of Keil (along with Legacy patches) and the SDK, I get the following messages when I try to open the ble_app_template_s110 project:

The project does build. But when I try to download it I get the following messages:

The log looks like this:

I see other questions here from people with the same problem and the fix seems to be an "uninstall" and reinstall. That didn't work for me but I suspect it's because I'm not sure what an "uninstall" consists of. Is there a step-by-step list of what steps I need to do for an uninstall to fix this problem?

Copy paste from your post here:

It looks like you are using old J-Link USB drivers. So first please try to upgrade your drivers. You'll find the latest J-LInk drivers here and you can update the Segger IC firmware on your kit by using the Segger J-Link Configuration tool. I don't really think it is the drivers that are causing your problems though.

Have you installed the latest Microcontroller Development Kit, nRF5x_MDK_8_0_3_Keil4 found in the SDK zip file?

Have you seen this and this link?

I updated the J-Link USB drivers and Segger firmware and it didn't help.

I verified that the version of the SDK that I have installed is the same as the one referenced above (9.0.0_2e23562).

I tried to follow this set of instructions: link

But the Nordic device is not in the list of flash download targets. I guess something is going wrong with the SDK installation. Are there some installer logs somewhere I can look at?

In the second link you provided, it looks like they never did get the Keil environment to properly download the firmware and ended up just using the nRFgo studio to do it. Is that the recommended solution, to abandon downloads with Keil? Will Keil still work for source-level debugging even if it won't work for downloading?
