Can't start latest AWS CLI on Windows (malformed path to config file)

Question

I've just just installed the latest AWS CLI x64 on Windows 10, from file AWSCLI64.msi .  Then I have set the PATH variable as required.  
When I launch aws, I get the following error:

```
C:\Users\Sergio>aws --version
Traceback (most recent call last):
  File "aws", line 27, in 
  File "aws", line 23, in main
  File "awscli\clidriver.pyc", line 55, in main
  File "awscli\clidriver.pyc", line 63, in create_clidriver
  File "botocore\session.pyc", line 386, in full_config
  File "botocore\configloader.pyc", line 152, in raw_config_parse
botocore.exceptions.ConfigParseError: Unable to parse config file: C:\Users\Sergio/.aws/credentials
```

The last line clearly suggests the cause, as the path to credentials file is malformed for Windows: **C:\Users\Sergio/.aws/credentials**  
indeed, it should be:  **C:\Users\Sergio\.aws\credentials**  
  
Hence, I've set the env variable
 `AWS_CREDENTIAL_FILE=C:\Users\Sergio\.aws\credentials`
, then opened a new cmd.exe window, but I still get the same error.  
  
I've also tried the command:

```
aws configure
```

but the same error occurs too.   It seems aws.exe cannot start in any way on Windows.  
  
What should I do ?  
(and please, let AWS fix this bug !)

Answer

I have just discovered that the error is due to an invalid format of .aws\credentials file content.  
It can be solved by editing the file and placing there proper credentials, following the format shown here:

Anyway, to get a useful tip which addressed me to the resolution, I had to uninstall AWSCLI from its MSI installer package and then reinstall it using pip:

```
pip install awscli --upgrade --user
```

After some more troubleshoot of PATHs, I ran **aws** again and I got a more meaningful error message, which addressed me to the resolution above.
