Opened in safe mode and etc. I had to replace my disc drive so had to isntall a new operatingg system i upgraded to windows pro. that dll was working originally now having issues its that dll file thats causing issue but this is the error i get i have other dll's working for eg user contributedstudies.dll it is just giving an erro for JP_Collection_64.dll Since its loading the other dll files so i am not sure if the issue is with dll file. 2025-04-03 15:07:03.069 | Found DLL: C:\SierraChart\Data\UserContributedStudies.dll 2025-04-03 15:07:03.073 | JP_Collection_64.dll loading error. Windows error code 126: The specified module could not be found. 2025-04-03 15:07:03.073 | InternalVersionNumberToFileNameMap is empty for JP_Collection 2025-04-03 15:07:03.073 | Closest match search for: C:\SierraChart\Data\JP_Collection.dll returned empty result.

Hi - Based on my experience with a similar error, this is because the fresh Windows install is missing some random support .dll file that the custom study depends on. In my case I solved it by installing Visual Studio, which deposits a bunch of library .dll files on the install disk. If you do install Visual Studio you can use the dumpbin tool to see what dependencies your study .dll may have. https://visualstudio.microsoft.com/downloads/ Hope that helps! |

In my case, yes. The Visual Studio installation includes various support libraries (.dll files) that provide a bunch of standard C and C++ APIs that people (custom study developers) just take for granted. Once those libraries were present, the custom study I had that was failing due to a missing .dll was happy. |

Full install of visual studio should not be necessary (if it is missing libraries due to wrong compiler option set in VS).

Yes. That's what I thought (was hoping) too. However, after trying installing just the standard library distros from the MS website, the problem custom study was still failing. That's when I decided to just do the full VS install, which did resolve the problem. I think I just installed the Visual Studio components needed for C and C++ development.

Hi 447693 - >> JP_Collection_64.dll loading error. Windows error code 126: The specified module could not be found. This is the same error I was seeing in my situation, and the custom study would not even show up in the Add Studies dialog, indicating that Sierra couldn't get the DLL to load properly when it scanned for all the custom studies because of the error. If you did the install of Visual Studio, and installed the components required for C and C++ development, AND then rebooted your PC and then started Sierra with all the Visual Studio stuff in place, and it's still not working, you may want to try contacting the developer of the problematic custom study for support. Oh... one more thing... my problem DLL was working fine on a Win11 system that had been upgraded from Win10. It only started failing when I tried to use it on a fresh install of Win11. FWIW, I installed "Visual Studio 2022", which solved the issue in my case. Date Time Of Last Edit: 2025-04-03 22:07:48

Glad you got it working! Can you post the URL for the C++ libraries download to this thread? It may help someone else at some point. Cheers! |

All I downloaded Visual studios. I see visual studios in my programs but i didnt see c++. I tried to activate it still the dll file wouldnt work so i went on microsoft site and downloaded c++ https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170 I downloaded the x64 https://aka.ms/vs/17/release/vc_redist.x64.exe The file is "microsoft visual C++ 2015-2022 redistributable (x64)" I think the visual studios would have worked but it never extracted the c++ so i had to download C++ The dll file that i had didnt come packaged with c++. It was looking for c++ libraries. This issue i guess will not happen if you buy a new computer but when you erase the entire drive and load a new operating system it does not load .net, or c++ libraries Thank you all who have helped me. I hope this is helpful to people who are having issue with dll files. Date Time Of Last Edit: 2025-04-04 15:39:46
