+## I get a "Microsoft Edge can't read or write to its data directory" error when running my program as admin on Windows
+
+You set your program to require admin permissions and it worked great! Unfortunately, some users are seeing a "Microsoft Edge can't read or write to its data directory" error when running it.
+
+When a Windows machine has two local accounts:
+
+- Alice, an admin
+- Bob, a regular user
+
+Bob sees a UAC prompt when running your program. Bob enters Alice's admin credentials into this prompt. The app launches with admin permissions under Alice's account.
+
+Wails instructs WebView2 to store user data at the specified `WebviewUserDataPath`. It defaults to `%APPDATA%\[BinaryName.exe]`. 
+
+Because the application is running under Alice's account, `%APPDATA%\[BinaryName.exe]` resolves to `C:\Users\Alice\AppData\Roaming\[BinaryName.exe]`.
+
+WebView2 [creates some child processes under Bob's logged-in account instead of Alice's admin account](https://github.com/MicrosoftEdge/WebView2Feedback/issues/932#issue-807464179). Since Bob cannot access `C:\Users\Alice\AppData\Roaming\[BinaryName.exe]`, the "Microsoft Edge can't read or write to its data directory" error is shown.
+
+Possible solution #1:
+
+Refactor your application to work without constant admin permissions. If you just need to perform a small set of admin tasks (such as running an updater), you can run your application with the minimum permissions and then use the `runas` command to run these tasks with admin permissions as needed:
+
+```go
+//go:build windows
+
+package sample
+
+import (
+    "golang.org/x/sys/windows"
+    "syscall"
+)
+
+// Calling RunAs("C:\path\to\my\updater.exe") shows Bob a UAC prompt. Bob enters Alice's admin credentials. The updater launches with admin permissions under Alice's account.
+func RunAs(path string) error {
+    verbPtr, _ := syscall.UTF16PtrFromString("runas")
+    exePtr, _ := syscall.UTF16PtrFromString(path)
+    cwdPtr, _ := syscall.UTF16PtrFromString("")
+    argPtr, _ := syscall.UTF16PtrFromString("")
+
+    var showCmd int32 = 1 //SW_NORMAL
+
+    err := windows.ShellExecute(0, verbPtr, exePtr, argPtr, cwdPtr, showCmd)
+    if err != nil {
+        return err
+    }
+    return nil
+}
+```
+
+Possible solution #2: change `WebviewUserDataPath` to a path writeable by both Alice and Bob. 
+
+Possible future solution #3: [run WebView2 using an in-memory mode if implemented](https://github.com/MicrosoftEdge/WebView2Feedback/issues/3637#issuecomment-1728300982).

 ## WebView2 installation succeeded, but the wails doctor command shows that it is not installed
 
 If you have installed WebView2, but the `wails doctor` command shows that it is not installed, it is likely that the
 WebView2 runtime installed was for a different architecture. You can download the correct runtime from [here](https://developer.microsoft.com/en-us/microsoft-edge/webview2/).
