I have a small python COM server that worked fine with Excel until I
decided to import the standard Python 'uuid' module.

Now I get the Windows Runtime error R6034 "An application has made an
attempt to load the C runtime library incorrectly"

I there anything that I can do to fix this?

Which version of Python are you running?
32 or 64 bit?
Which version of pywin32?
Which version of Windows?
Can you make a small test case that will demonstrate the error?

OK, sorry, here are some more details.

I have Python 2.7.8, win32, running on a Windows7 64-bit home machine (not
professional).

Here is my python script:

#---------------------------------------
import pythoncom

#import uuid

class Bug:

_reg_clsid_ = '{E3D5F332-F080-47B3-A319-A3A0E287E466}'
_reg_progid_ = "BugServer"
_public_methods_ = ['hello']

def __init__(self):
pass

#------------------------------------------------------------------------
def hello(self,who):
return "Hello {}".format(who)

#============================================================================
if __name__=='__main__':

# cmd options: --register --debug and --unregister
import win32com.server.register
win32com.server.register.UseCommandLine(Bug)
#---------------------------------------------

As it is, this works fine. I just run the script with an Admin command
window to register the server. But when I uncomment the 'import uuid' line
the error occurs as Excel opens.

In my VBA code I have (in ThisWorkbook)

Private Sub Workbook_Open()
' When the workbook opens we create the object
Set Bug = CreateObject("BugServer")
Debug.Print "open"
End Sub

and in a separate module I have defined the UDF

Public Bug As Object
Function hello(ByVal expr As String) As Variant
'
'
hello = Bug.hello(expr)

End Function

Thanks for the help.

Hi!

I test with my own Python-COM-server (Ponx), and I have also an error:

---------------------------------------------------------------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Runtime Error!

Program: D:\Dev\Python\PonxTest101.exe

R6034

An application has made an attempt to load the C runtime library
incorrectly.
Please contact the application's support team for more information.
---------------------------------------------------------------------------------

I use Python 2.7.3 and Pywin32.218 on Win-7-64 bits.
If I comment the line, like: #import uuid the problem
disappears

I have just tried this same project on a computer with Win7-64 Professional
and MS Office 2010 (but with the same 2.7.8 32-bit Python installation).

The error does NOT occur.

So, is it the difference between Win7 for Home users and professional, or
is it something to do with MS Office (the bug occurred with MS Office 2007
on Win7-64 Home edition)?

This appears to be due to way rpcrt4.dll is loaded by ctypes. If a side-by-side assembly has already loaded a version thatâs not
compatible with the activation context of Python itself, ctypes will attempt to use it anyway.
