How to handle error 2755 when installing software under windows

Because there was an error when installing some MSI installer on windows on your computer before:

If you search for this error from Baidu, the general solution is to right-click the attribute, then modify the file permissions in the security group and check all the permissions that should be given. I have tried this method, but I still report the same error.

Later, find a method from the Internet:

Check whether the computer C: \ windows \ installer folder exists. If it does not exist, create a folder and grant administrator permission.

Then copy the installer to the installer folder and execute.

During re execution, the following new errors are found:

At this time, I tried to change the file permissions and found that it didn’t work. Maybe I changed it in the wrong way. At this time, I changed the way. Open the CMD window as an administrator, enter the C: \ windows \ installer directory, and then enter the file name of the installer to complete the installation.

A download error occurred while downloading data from pytorch. Urllib.error.urlerror: < urlopen error [SSL: certificate_verify_failed]

The reason is that the SSL certificate needs to be verified, but the certificate verification failed. I tried some methods on the Internet, mainly including canceling certificate verification and installing the latest certificate. I didn’t find a suitable method to install the latest certificate, so I used the method of canceling certificate verification. The specific operation is to add the following code at the location where the file needs to be downloaded:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context
