So I installed it and it says: program can't start because mvcp71.dll is missing from your computer. What kind of file is this?

A short investigation reveals this message

 

Traceback (most recent call last):
  File "SC4PIM.py", line 1, in ?
  File "SC4PIMApp.pyo", line 96, in ?

It's a Microsoft system file that's not present on every Microsoft OS.  If you Google it, you can find a place where you can download it for free.  Then install it in your SysWOW64 directory under Windows, or System32 if you're running a 32-bit version of Windows.

 

And very important:  The file's name is msvcp71.dll.

    It's a free file, so it can't be pirated.  One reliable place you can download it from is here.

    The program is written in Python.  MS doesn't generally distribute the run time library, but it is available from them.  Their download centre will dispense it free.  What you need is the python run time library.

     

    Python is an unusual language on this side of the ditch.  Generally things like this are written by university students.  Python is an annoying substitute for C++.  Annoying because it is positional and not context free.  One wrong tab, and welcome to the world of serious debugging.

    If you are missing the MSVCP71.DLL file, then you need to install Microsoft Visual C++ Redistributable (x86) package, I think version 2008. Note, you need the 32-bit file, because the application is 32-bit.

    Hi, I'm experiencing the same trouble with PIM. I'v installed it but it show me this error:

    ''Traceback (most recent call last):
      File "SC4PIM.py", line 1, in ?
      File "SC4PIMApp.pyo", line 96, in ?
      File "wx\__init__.pyo", line 45, in ?

      File "wx\_core_.pyo", line 12, in ?
      File "wx\_core_.pyo", line 10, in __load
    ImportError: DLL load failed: The specified module could not be found..''

    However, I installed the Microsoft Visual C++ Redistributable Package but I continues showing me the same error, and I can't run it.

    Hi,

    looks like it could be a dll issue. For starters, do you have the four dlls specified in the documentation installed?

    "If you have a problem running SC4PIM:
    -Download the GLU32.dll and GLUT32.dll from http://www.dll-files.com/ and put them in SC4PIM folder
    -Download the GDIPLUS.dll from http://www.dll-files.com/ and put it in SC4PIM folder
    -Download the MSVCP71.DLL  from http://www.dll-files.com/ and put it in SC4PIM folder"

    Thanks I will try. But I don't know if the fact I purchased SC4 from steam might be the cause

    Steam doesn't affect this, since SC4 PIM is a 3rd party application, those .DLL files (the ones it can't find), contain snippets of code needed for the application to function. In order for it to see these .DLLs, they not only need to be present on your computer, but one of the following conditions must also apply:

    1. The .DLLs are installed such that they are located in a system folder defined in Windows.
    2. The .DLLs are located in the same folder as the main application (SC4PIM.exe), and the application has sufficient access to read them.

    To begin with, just search in Windows for the necessary .DLLs, many users already have these common files. Any that you find, copy to the SC4PIM install folder. Then you can try to download any that remain, but I'm not sure the original links given are very trustworthy. I did detail once which packages contain which .DLLs, these files were not officially meant to be distributed standalone. I'd take me a while to find the post, but I will attempt to find time to do so. If after having all the files in the install folder, you still see the error, most likely it's a Windows permissions issue. Tell Windows to give the application Administrator access by right clicking upon the .exe file and selecting, Run as Administrator. This should hopefully allow the application to find and load the required code libraries, think of them as Dependencies, but for SC4PIM rather than a mod.

    If you can recall specific words which would be in said post, we can ask @Cyclone Boom to use his database search magic and prolly have a much better chance of finding it than using our woefully inadequate site search or even Google.

    Thanks you so much guys! Yes, it was a dll's issue, but I followed thingfishs steps and PIM and Lot editor run very well image.png.4f1c0e473ebe2fc3c5017b553213d8f0.png

    I recall something related to an OpenGL or OpenCL package, along with the C++ Redistributable. Likely also the .dll names too, that should narrow it down I think.

    Apologies for having to bring this subject up again, but I am experiencing the same problem...

    I followed your two steps and have the dlls in C:\Windows\System32 as well as the PIMX folder (I do run it as administrator). Any other suggestions ?

    If you are using a 64-bit OS, that's no longer the right system folder, it would be in SysWOW64, but they may still require the correct system links or no app would know to look there. This only happens when these files get installed rather that coming as loose .dlls.

    But logically either there is a problem with one of the .dll files, the date on GdiPlus.dll looks suspiciously new, it's possible the file doesn't contain the API needed by SC4-PIM if it got depreciated as part of an update? Then again, it's equally possible that you need a newer version for your hardware, really hard to say.

    The other possibility is some security restrictions mean even when ran as Admin, the App is still not able to access the libraries (.dll files) as required. A way to test this would be to uninstall the App and re-install it away from any system protected folders like Program Files (x86) or even Users. If it still fails to work with the .dll files in the install folder, then I'd look for an older version of GDI Plus, which came from one of the C++ redistributables.
