import win32api error in Python 2.6

When running python26 under windows OS (64bits)..... I have got errors like:

import win32api" error in Python 2.6: pywintypes26.dll

pythoncom26.dll missing
ImportError: DLL load failed: The specified module could not be found.

I have done the msi installation for python26 all dlls can be found under C:\Python26\Lib\site-packages\pywin32_system32

Solution 1:

After I copy pywintypes26.dll and pythoncom26.dll from C:\Python26\Lib\site-packages\pywin32_system32 to C:\Python26\Lib\site-packages\win32 -> Solve the problem!

Solution 2:

I also hit a problem importing win32api.

The post-install script for pywin32 failed, which should copy pythoncom26.dll, pythoncomloader26.dll, and pywintypes26.dll, among other things. I ran it by hand and my installation was fixed.

python scripts\pywin32_postinstall.py -install

Solution 3:

I had a similar problem when installing under 64 bit Python 3.4.2. I ran the install executable pywin32‑219.win‑amd64‑py3.4.exe from http://www.lfd.uci.edu/~gohlke/pythonlibs/ .

On the site it states clearly:

"Python 3.4 users must manually run python.exe Scripts\pywin32_postinstall.py -install from an elevated command prompt."

which I did not do first time round; I installed from a normal prompt getting the following feedback:

c:\python34>python.exe Scripts\pywin32_postinstall.py -install
Copied pythoncom34.dll to C:\Python34\pythoncom34.dll
Copied pywintypes34.dll to C:\Python34\pywintypes34.dll
You do not have the permissions to install COM objects.
The sample COM objects were not registered.
etc.etc.
Finishing with "The pywin32 extensions were succesfully installed" ...

I only read the last sentence and I started to run some code resulting in getting these dll load fails.

So, did some research, and started an elevated prompt (how: see "http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html") and again ran:

c:\python34>python.exe Scripts\pywin32_postinstall.py -install
Copied pythoncom34.dll to C:\Windows\system32\pythoncom34.dll
Copied pywintypes34.dll to C:\Windows\system32\pywintypes34.dll

The pywin32 extensions were successfully installed.

And now my code runs happily (as far as this matter is concerned... sigh, so much other stuff to do).

Solution 4:

Run the installer as Administrator and it works:

Right click on pywin32-installer.exe
Choose "Run as Administrator"

Solution 5:

As suggested above the post install script is not run, this issue can be seen when installing from a wheel (As I encountered)

python scripts\pywin32_postinstall.py -install

If find you have this issue when installing via wheels, then installing it from here can solve the above issue.
