Recently, I am trying to do a project related to Bluetooth, which requires the use of the nRF52832 chip. In order to import the protocol stack hex, you need to use nRFgo Studio software.
However, the most important column of the installed software, nRF5X Programming, is grayed out and cannot be used; in addition, you can also see the following prompt column: JLinkARM.dll is not correctly installed. Please run the nRF Tools installer to install the newest version. So I started trying to solve it.
一、解决"JLinkARM.dll is not correctly installed. Please run the nRF Tools installer to install the newest version."
First, according to most of the solutions recommended on the Internet, use the win+R shortcut key, enter "regedit" to open the registry editor. In its directory: Computer\HKEY_CURRENT_USER\SOFTWARE\SEGGER\J-Link;
With: COMPUTER\HKEY_LOCAL_MACHINE\SOFTWARE\SEGGER\J-Link;
With: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SEGGER\J-Link;
Check with: Computer\HKEY_USERS\S-1-5-21-1617176480-2471675625-1873805384-500\SOFTWARE\SEGGER\J-Link, check and modify it to the actual installation path. For example, my path is: D:\JLink_V612a. (Here is my installation path, which is installed on the D drive, and it can also explain that it is not necessary to install all the drivers on the C drive)
This solves the prompt problem of "JLinkARM.dll is not correctly installed. Please run the nRF Tools installer to install the newest version.". But unfortunately, nRF5X Programming is still grayed out. By the way, the above paths are not necessarily all wrong, and may not all need to be modified, but you can still check them all. In fact, I only changed one thing and it solved the problem.
2. Solve the problem that nRF5X Programming is displayed in gray
During the installation of nRFgo Studio (version 1.21.2), I found that the software will automatically install a JLink driver (version V5.12f) for me. Therefore, I did not install the driver (version V6.12a) required by the tutorial of the development board. Later, when troubleshooting the problem, I thought it might be this: the driver version does not match the nRFgo Studio version, even if the existing driver is installed by default. So I uninstalled the V5.12f version, installed the V6.12a version, and finally solved the problem that nRF5X Programming is displayed in gray.
Here is the download address of the V6.12a driver:

3. A step that is useless to me but still needs to be checked
When looking for solutions on the Internet, I also saw a point worthy of attention that may be able to help everyone solve the problem. It is to open the jlink.exe program in the installation directory, and check whether the jlink S/N number prompted by the program is -1.
Glad mine wasn't, but a string of date-like numbers:
But if it is, you can execute the "exec setsn=XXXXXXXX" command under jlink.exe, where XXXXXXXX is the new S/N number, and the number is random. Thus to solve this problem.
The above is my record of "nRF5X Programming Display Gray Solution in nRFgo Studio", I hope it will be helpful to everyone.
