[python-win32] Python 3.7: difficulties importing adodbapi after installation

[Sibylle Koczian]

Fresh install of Python 3.7 on Windows 10.

Installed pywin32-223.win-amd64.py3.7.exe (from python.org) without 
error messages, but the adodbapi directory didn't contain apibase.py and 
so adodbapi couldn't be imported.

Next step: "pip install adodbapi --upgrade" again seemed to work 
normally, but now 4 files contained line endings "\r\r\n":
apibase.py
is64bit.py
process_connect_string.py
server.py
This caused an IndentationError at the first line continuation in 
apibase.py (whitespace after the \):
line 249, pythonDateTimeConverter.DateObjectFromCOMDate,
         dte=datetime.datetime.fromordinal(integerPart + 
self._ordinal_1899_12_31) \
             + datetime.timedelta(milliseconds=floatpart*86400000)

I couldn't find differences to the module version in my Python 3.6 
installation, other than the line endings, so I copied the 4 files from 
there.

Last problem: now adodbapi missed 
...\python37\lib\site-packages\win32com\gen_py\dicts.dat. The second 
exception in the traceback said something about missing rights, so I 
opened a Python shell as administrator and imported adodbapi there. That 
created the file.

Now everything works as it should, but why the hassle?
