In my previous bug report, I was told that I had a mixture of old and new installs. So I ran MikTeX console uninstall (again), deleted the MikTeX folders, (again). ran the install (again) and got the same error. So how does one remove all traces of previous installations?

Windows API error 127: The specified procedure could not be found.

dllName="C:\Program Files (x86)\MiKTeX 2.9\miktex/bin\MiKTeX209-core.dll"

There is no C:\Program Files (x86)\MiKTeX 2.9 folder. Root3 should be C:\Program Files\MiKTeX 2.9 but I don't know how to fix it.

You have to remove MiKTeX by hand:

rmdir /S /Q "C:\Users\John\AppData\Roaming\MiKTeX\2.9"
rmdir /S /Q "C:\Users\John\AppData\Local\MiKTeX\2.9"
rmdir /S /Q "C:\ProgramData\MiKTeX\2.9"
rmdir /S /Q "C:\Program Files (x86)\MiKTeX 2.9"

You also have to delete the registry keys:

• HKEY_LOCAL_MACHINE\SOFTWARE\MiKTeX.org\MiKTeX\2.9
• HKEY_CURRENT_USER\Software\MiKTeX.org\MiKTeX\2.9

I ran uninstall first to see what was being removed automatically. All the folders except "C:\Program Files\MiKTeX 2.9" were already gone, and (using regedit) I couldn't find the registry keys to be deleted (or anything involving MikTeX). I got as far as HKEY_LOCAL_MACHINE\SOFTWARE\ and HKEY_CURRENT_USER\Software\.

[elfsoft2000]

Using the "Find..." facility of regedit I did find three registry keys using MikTeX (under Classes). Going to try to reinstall now.

[elfsoft2000]

Nope. Same error.

[elfsoft2000]

I searched the registry for every pathname including MikTeX and found nothing involving Program Files (x86).

[elfsoft2000]

I searched again for MiKTeX this time and found it. It still doesn't work, but is looking in the right folder now.

I am having the same problem:

1. Uninstallation done as per edocevoli's instructions.
2. A fresh installation (v 2.9.6850-x64) without errors.
3. 96 updates found.
4. Update (in the console) proceeds to give "Update in progress... we're almost done" gives an error message:
   miktex-console.exe - Entry Point Not Found
   (x) The procedure entry point
   ?Start@StopWatch@Trace@MiKTeX@@sa?AV?$unique_ptr@VStopWatch@Trace@MiKTeX@@U?$default_delete@VStopWatch@Trace@MiKTeX@@@std@@@@@PEAVTraceStream@23@AEBV?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@5@1@Z could not be located in the dynamic link library MiKTeX209-trace.dll.
5. The console gives an error report with the details:

Windows API error 127: The specified procedure could not be found.

dllName="C:\Program Files\MiKTeX 2.9\miktex/bin/x64\MiKTeX209-core.dll"

6. I try to uninstall, getting a similar Entry Point Not Found error.
7. The console claims (incorrectly) uninstallation as succesful.

You can always just delete the " C:\Program Files\MiKTeX 2.9" folder and reinstall, but that is (probably) how I wound up with bad registry keys. BTW, I don't think they pay any attention to "Closed" reports.

Good to know, elfsoft2000.

I found some help and workarounds from issue 187: #187. For me, installing only for me and using some commands after error messages helped.
