            Bug ID: 140278
           Summary: Embedded Python install missing 6 Windows DLL files
                    (LO 7.1.0.3, Python 3.8.4)
           Product: LibreOffice
           Version: 7.1.0.3 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Installation
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
After upgrading from LO 7.0 to 7.1.0.3, I am unable to install "pip" using
"get-pip.py" on a Windows 10 PC. Traceback from get-pip shows error
  FileNotFoundError: [WinError 2] The system cannot find the file specified 
However, as explained below, the error / traceback are a bit of a red herring.
I think the real issue is that 6 DLL files are missing from the embedded python
installation delivered with LO 7.1.0.3.

There is a workaround, but it would not be easy for non-technical users.

Steps to Reproduce:
1. Perform standard upgrade installation of LO 7.1.0.3 on Windows 10 PC
2. Open administrator powershell
2a. cd 'C:\Program Files\LibreOffice\program\'
2b. curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
2c. .\python.exe .\get-pip.p

Actual Results:
PS C:\Program Files\LibreOffice\program> .\python  .\get-pip.py

Traceback (most recent call last):

Additional Info:
Possible workaround:
I suspected that some Windows-specific files might be missing from the embedded
python distribution included with LO 7.1.0.3. Using source from
https://www.python.org/ftp/python/3.8.4, I first checked *.pyd files, but they
all seemed to be present (though I only spot-checked, did not exhaustively
compare).  Next I checked *.DLL files and found only 2 on the target PC, but 8
in the master ZIP file.  See list below:

 Status                 Name
 ------                 ----
 present                libcrypto-1_1.dll
 present                libssl-1_1.dll

 Missing                libffi-7.dll
 Missing                python3.dll
 Missing                python38.dll
 Missing                sqlite3.dll
 Missing                vcruntime140.dll
 Missing                vcruntime140_1.dll

After copying the 6 missing DLL files to: 
    C:\Program Files\LibreOffice\program\python-core-3.8.4\lib\
I re-ran step 2c above and succeeded in installing pip.  I was also able to
install other packages using pip.  I have not done any further testing, but it
seems this might be a workaround until the problem is resolved (though not
suitable for non-technical users).
