安装pywin32出现--Python version 3.3 required, which was not found in the registry

前天安装pywin32时出现了这个问题

双击.exe文件进入安装界面，然后点击下一步，它会自动定位你的python安装在什么地方，但是我的安装过程显示

安装pywin32出现--Python version 3.6 required, which was not found in the registry

百度了一下，搜集了各方的解决方案，综合了起来，将问题解决了

解决方法：

步骤一：

新建一个register.py文件（我将其放在pywin32同一个文件下），双击打开

python3贴入以下代码并保存

from __future__ import print_function
 
 
import sys
 
try:
    from winreg import *
except ImportError:
    from _winreg import *
 
# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix
 
regpath = "SOFTWARE\\Python\\Pythoncore\\{0}\\".format(version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "{0};{1}\\Lib\\;{2}\\DLLs\\".format(
    installpath, installpath, installpath)
 
 
def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print("*** Unable to register!")
            return
        print("--- Python", version, "is now registered!")
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print("=== Python", version, "is already registered!")
        return
    CloseKey(reg)
    print("*** Unable to register!")
    print("*** You probably have another Python installation!")
 
if __name__ == "__main__":
    RegisterPy()

python2贴入以下代码并保存

import sys


from _winreg import *


# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix


regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
    installpath, installpath, installpath
)


def RegisterPy():
    try:
        reg = OpenKey(HKEY_CURRENT_USER, regpath)
    except EnvironmentError as e:
        try:
            reg = CreateKey(HKEY_CURRENT_USER, regpath)
            SetValue(reg, installkey, REG_SZ, installpath)
            SetValue(reg, pythonkey, REG_SZ, pythonpath)
            CloseKey(reg)
        except:
            print "*** Unable to register!"
            return
        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"


if __name__ == "__main__":
    RegisterPy()

步骤二：保存之后进入cmd，切换到存储该py文件的目录，执行python registed.py即可重新运行exe文件进行pywin32的安装。

成功时的界面：然后点击下一步即可

另：

若安装成功后在pycharm中 import win32api 时报错找不到该模块，在cmd中 import win32api 也报错

dll load faild:%1 不是有效的win32程序

解决方法：pywin32的安装程序的名称中的32和64位并不是针对电脑的，而是python，有的人的电脑是64位的而python是32位的（查看python信息，打开cmd，输入python即可查看），可以重新安装32位的pywin32。 

除此之外，在高级设置中添加环境变量python\Lib\site-packages之后，重启下pycharm就可以在pycharm中  import win32api 了。
