I can't download a ZIP file from the Sitefinity CMS Export / Import menu

I want to download a ZIP file from Sitefinity CMS Export / Import menu, but after I clicked "Export to ZIP file" button I've got this error: Data have not been successfully exported. I've tried to export each item individually, but the result was still the same.
Steps to reproduce:
Go to Sitefinity CMS (Admin site) -> Administration -> Export / Import -> Download ZIP file -> select just 1 item -> click "Export to Zip file" button -> the error appears on the Browser: Data have not been
successfully exported.
Detail error message,
On the CMS: Data have not been successfully exported
On the Chrome DevTools:

When calling OpenSubKey from C# application, getting Security Exception error and the application is not launching

When calling OpenSubKey Registry function from the C# application, getting the below exception and because of this application is not launching.
Application: EMR.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.Security.SecurityException at System.ThrowHelper.ThrowSecurityException(System.ExceptionResource) at Microsoft.Win32.RegistryKey.OpenSubKey(System.String, Boolean)
Below is the Registry key value passing into the openSubkey
HKEY_LOCAL_MACHINE\SOFTWARE\EMR\4.01.00\Technical Data
And one more thing is, after installation first time I am able to launch the application. But Once restart the machine then when trying to launch I am seeing this error.
Below is the code snippet:
public RegistryKey GetRegKeyHandle(String key)
{
key = BASE_REG_KEY + "\\" + key;
if (MainFrame.GetUIControlObject().MGDIsAdmin())
{
MessageBox.Show("Entered to MGDIsAdmin");
regWritable = true;
RegistryKey rkTest = Registry.LocalMachine.OpenSubKey(key, true);
return rkTest;
}
else
{
return Registry.LocalMachine.OpenSubKey(key);
}
}
Please help me why it is throwing security exception only after restart?

WPF app not exiting because of UWP PdfDocument

I'm trying to use the UWP Windows.Data.Pdf API from a WPF-Desktop app. It can render a PDF page to a PNG image just fine.
The issue I have is that after executing the PDF rendering, closing the WPF-Window does no longer exit the application. The process keeps running. I tried pausing the application in the debugger in this state, but no application code appears to be running. Some thread or resource must still be open, I guess.
My question here is does anybody have any idea why this happens? And furthermore, how can I debug this kind of issue?
The issue is reproducible with the empty WPF template in VS17, I added to the .csproj:
<TargetPlatformVersion>10.0.16299.0</TargetPlatformVersion>
...
<Reference Include="System.Runtime.WindowsRuntime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, processorArchitecture=MSIL">

</Reference>
<Reference Include="Windows">
<HintPath>$(MSBuildProgramFiles32)\Windows Kits\10\UnionMetadata\10.0.16299.0\Windows.winmd</HintPath>
</Reference>
From a simple button I'm executing this code:
using System;
using System.Runtime.InteropServices.WindowsRuntime;
using System.Threading.Tasks;
using Windows.Data.Pdf;
using Windows.Graphics.Imaging;
using Windows.Storage;
using Windows.Storage.Streams;
...
var filename = #"C:\Users\...\a.pdf"
var f = await StorageFile.GetFileFromPathAsync(filename);
byte[] content;
using (var stream = await f.OpenReadAsync())
{
var d = await PdfDocument.LoadFromStreamAsync(stream);
using (var page0 = d.GetPage(0))
{
await page0.PreparePageAsync();
using (var randomAccessStream = new InMemoryRandomAccessStream())
{
await page0.RenderToStreamAsync(randomAccessStream, new PdfPageRenderOptions { BitmapEncoderId = BitmapEncoder.PngEncoderId });
content = new byte[randomAccessStream.Size];
await randomAccessStream.ReadAsync(content.AsBuffer(), (uint)randomAccessStream.Size, InputStreamOptions.None);
}
}
}
File.WriteAllBytes(#"C:\Users\...\b.png", content);
This is almost the entire code, but in case I missed something I also pushed it to https://github.com/marv51/PDFRendererNotExiting
Thank you very much in advance for any help on this.
Update:
I just observed, that the process does eventually exit after about 2 minutes!
Probably related, I found in the event viewer:

So I assume some background thread crashed during termination and Windows Error Reporting keeps the process alive to collect information. Or some kind of timeout kills open resources?
I'm sorry, I just found this. Can I do anything with this crash Information?
Update 2
After spending a lot of time on this and learning some windbg, I think this might be an Nvidia graphics driver crash:
Attaching to the app and then closing the window shows this exception:
(2134.1cac): Unknown exception - code 0000071a (first chance)
(2134.1cac): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

I posted the analyze -v output here: https://gist.github.com/Marv51/d3ad0e9a49b6c985d9116600fd0475b7
From looking at the stacktrace I believe the destructor for the internal class Windows.Data.Pdf.CPdfStatics tries to release some DirectX resources and the Nvidia driver corrupts the heap during this process.
I tried updating to the latest Nvidia driver, which changed nothing.
Not sure where I can go from here. I'm still a windbg beginner, so I might interpret this output wrong.
Maybe the 'solution' for now is that I will do this work in an external process to avoid these issues from 'infecting' the main app.

Retrieving calls history from Windows 10 app - Access denied error

I'm trying to collect the Windows Mobile 10 calls history by using the latest API. I have enabled all possible capabilities for my application, but still I'm getting "Access Denied" error while running this code:
var operation = PhoneCallHistoryManager.RequestStoreAsync(PhoneCallHistoryStoreAccessType.AppEntriesReadWrite);
operation.Completed = (o, ev) =>
{
PhoneCallHistoryStore store = o.GetResults();
PhoneCallHistoryEntryReader reader = store.GetEntryReader();
var operation2 = reader.ReadBatchAsync();
operation2.Completed = (o2, ev2) =>
{
IReadOnlyList<PhoneCallHistoryEntry> callsList = o2.GetResults();
foreach (PhoneCallHistoryEntry entry in callsList)
{
// process calls here
}
};
};
I'm getting the following error message while doing line 4:
An exception of type 'System.UnauthorizedAccessException' occurred in App1.exe but was not handled in user code
Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I'm running this code on Mobile Emulator in Visual Studio 2015.
This is what I used for that code:
https://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.calls.aspx
Any idea what can be wrong?

In order to make above code working and view phone call history, need to add the following things:
1) Rescap namespace
xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
2) Restricted capability "phoneCallHistory"
<rescap:Capability Name="phoneCallHistory"/>
3) Change PhoneCallHistoryAccessType to AllEntriesLimitedReadAndWrite.
var operation = PhoneCallHistoryManager.RequestStoreAsync(PhoneCallHistoryStoreAccessType.AllEntriesLimitedReadWrite);
Thanks to #RaymondChen for giving me the proper capability name.

Firefox crash when I run selenium unit test

I start use Selenium.WebDriver (v2.45) to run visual tests.
As web driver I use FirefoxDriver. I have installed Firefox 38. When I try run test firefox return exception with message:
FF has stopped working.
Does anyone have any suggestions? It worked in previous week, is it possible that my test was crashed by updated?

There is my test method body:
[Fact]
public void ShouldLoginForTestAccount()
{
var driver = new FirefoxDriver();
driver.Manage().Cookies.DeleteAllCookies();
driver.Navigate().GoToUrl(LoginPage);
driver.FindElementById("Login")
.SendKeys("correctLogin");
driver.FindElementById("Password")
.SendKeys("correctPassword");
driver.FindElementByTagName("button")
.Click();
Assert.Equal(TestingProjectUrl, driver.Url);
driver.Close();
}

Selenium 2.45 does not reliably work with Firefox 38 due to compatibility issues.
Downgrade Firefox to 35 (link to 35.0.1).

I have a suggestion.
I was getting the error bellow when I called Quit() method of WebDriver.
unknown software exception (0x80000003) em 0x55fdec79
So I created the WebDriver as follow:
FirefoxOptions foxOptions = new FirefoxOptions();
foxOptions.SetPreference("dom.allow_scripts_to_close_windows", true);
driver = new ThreadLocal<IWebDriver>(() => { return new FirefoxDriver(service as FirefoxDriverService, foxOptions, new TimeSpan(0, 1, 0)); }).Value;
Then, before call Quit() method, I execute one javascript to close the main window:
try { ((IJavaScriptExecutor)driver).ExecuteScript("window.close();"); } catch { }
So now I'm able to call Quit() without get any error. I know that this is a workaround, but I think this can help you.
