请问一下楼主,安装完毕之后,打开还是会出现“proxy host not found
http://www.stata.com did not respond or is not a valid update site
unable to check for update; verify Internet settings are correct.
”这样的红字,而且网络数据调用会出出现“PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
r(5100);"这怎么解决呢?万分感谢
