Error -153 from NRFJPROG_open_dll

[SteamingGizmo]

Hello,

I am attempting to update a custom C# application that is utilizing the NRFJPROG dll.
We are hoping to add compatibility for multiple programmers connected to the same PC.
To utilize this we plan on tracking multiple instances of the DLL using the functions that allow passing in of the instance variable.

However, we are getting error -153 or NRFJPROG_HOST_EXE_NOT_FOUND returned from NRFJPROG_open_dll_inst().
Changing this back to using the non instance controlled version (i.e. NRFJPROG_open_dll()) works correctly and does not return an error.

Could I get some more information on what causes error -153?

Thanks

Hi, 

It's caused by the nrfjprog library not being able to find the jlinkarm_nrf_worker.exe file. Please make sure that you have copied this file as well when deploying the nrfjprog dlls. It should be located in the same directory as the dlls, or in a structure similar to the one created by the nrfjprog installer.

Regards,
Amanda
