Before I use the Python 2.7.2 on Windows XP, today I tried to upgrade to the Python 2.7.3, but encountered a problem.
When running any .py file encountered "import unicodedata" or directly run the command always returns:
Traceback (most recent call last):
......
    import unicodedata
ImportError: DLL load failed: 找不到指定的程序。
"找不到指定的程序" corresponding English is "Cannot find the specified program".

I unable provide more information because I am only a user rather than developer.

After that, I manually delete "C:\Python27\DLLs\unicodedata.pyd" file (this step must be, otherwise no effect), then reinstall (Repair) Python 2.7.2 the problem disappeared.

I do not believe that this is a problem in Python. Instead, it appears that your Python installation got corrupted somehow.

I recommend to run a virus scanner.

I compared downloaded python-2.7.3.msi file, it is consistent with the website published "MD5 checksums and sizes", and this time I disabled avast 7 and then reinstall Python 2.7.3, but this error still occurs.

After I installed Python 2.7.3 the MD5 signature of the C:\Python27\DLLs\unicodedata.pyd file is: AD7DFE789B1256F039406B640ACD9C0D

I have not found that I had any operational errors.

I've had the same problem on a Win64 install of EPD 7.3 (Python 2.7.3). This was after installing over the top of a 2.7.2 install. Properly removing and re-installing from clean fixed the problem.
