当我尝试在计算机上安装VS 2017时，安装程序会给我以下错误，尽管我已经是管理员（是的，我已经尝试了＃34;以管理员身份运行＆＃34和乱搞UAC等...相信我，我已经尝试了所有常用的东西并知道Windows是如何工作的：
需要提升
此程序需要管理员权限才能执行设置操作 请以管理员身份重新运行该程序。
跟踪ProcMon，我在临时目录中看到一条似乎表明原因的日志：

似乎他们的代码是错误的，除非这只发生在我的机器上？为什么不是每个人都看到这个？是什么触发了这个问题，我该如何解决？

我最后通过安装.NET Framework 4.7解决了这个问题，但我怀疑更新4.0甚至更新的版本也可能有用。
问题似乎是// set one of viewcontrollers (usual first) as navigationController delegate
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.delegate = self
}
}
// make the view controller conform to `UINavigationControllerDelegate`
extension ViewController: UINavigationControllerDelegate {
func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationControllerOperation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return PushPopAnimator(operation: operation)
}
}
// The animation controller
class PushPopAnimator: NSObject, UIViewControllerAnimatedTransitioning {
let operation: UINavigationControllerOperation
init(operation: UINavigationControllerOperation) {
self.operation = operation
super.init()
}
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 0.25
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
let from = transitionContext.viewController(forKey: .from)!
let to = transitionContext.viewController(forKey: .to)!
let rightTransform = CGAffineTransform(translationX: transitionContext.containerView.bounds.size.width, y: 0)
let leftTransform = CGAffineTransform(translationX: -transitionContext.containerView.bounds.size.width, y: 0)
if operation == .push {
to.view.transform = rightTransform
transitionContext.containerView.addSubview(to.view)
UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
from.view.transform = leftTransform
to.view.transform = .identity
}, completion: { finished in
from.view.transform = .identity
transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
})
} else if operation == .pop {
to.view.transform = leftTransform
transitionContext.containerView.insertSubview(to.view, belowSubview: from.view)
UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
to.view.transform = .identity
from.view.transform = rightTransform
}, completion: { finished in
from.view.transform = .identity
transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
})
}
}
}
类中的一个错误，它不允许传递一个本来应该是合法的标志。我认为这是一个版本不匹配并修复。

我下载了VS预览https://visualstudio.microsoft.com/vs/preview/，然后再次正常运行

在我的情况下，原因是移除的驱动器上的TMP和TEMP环境变量，指向不可用的路径。
