Error installing and running pywin32 2.7

Question

I am coming up with a couple errors after installing:

pywin32-217.win32-py2.7

I have recently upgraded ArcGIS to 10.1 and it us

Answer 1

None of the solutions helped me (Sitting on Windows 10).

But I finally got it fixed when I ran c:\python27\scripts\pywin32_postinstall.py -install

After installation you can try to run the installer again just to be sure, worked for me.

Answer 2

You must not install as administrator, see this bug report:

This is maybe because you are running Windows under the "Administrator" account and anything you normally run is equal to a "run as Administrator"

And paradoxically running the installation of pywin32 on Windows 7 as Administrator causes this error.

So a workaround is to create another admin account

net user Admin /add
net user Admin
net localgroup Administrators Admin /add

and then run the pywin32 installation with

runas /user:Admin pywin32-217.win32-py2.7.exe

Answer 3

I solved it using this:

pip install pypiwin32

Answer 4

Steps to install pywin32 -

1. net user Admin /add
2. net user Admin
3. net localgroup Administrators Admin /add
4. runas /user:Admin pywin32-217.win32-py2.7.exe

Answer 5

I faced same issue when I installed pywin32-219.win-amd64-py2.7.exe by running the installer file as administrator.

Once I installed it by simply executing the file (double clicking on it), I didn't face this issue again.

I am on Windows 7 64 bit SP1 with Python 2.7.9 (64 bit)

However, I did notice one strange thing, if I just double clicked the installer exe it took slightly over 20 seconds for the prompt to appear whether I would like to run the exe file or not, whereas in case of running the file as administrator, it happened right then (didn't have to wait for that long) I am using 120 GB SSD so can't question the slowness of Hard disk in this case.

Anyways, here's the output after successful installation of pywin32 in my case:

Answer 6

I had the same problem, but solved it a bit differently. Instead of creating another admin account, I was able to execute the pywin32-217.win32-py2.7.exe successfully from a command prompt that I started with Run as Administrator.
