The code is signed using a certificate( NOT self signed ) as a requirement for this java version, on Windows 7 users are prompted to run/cancel launching the application, and if they check "Do not show this message.." and run the app, it launches successfully and the certificate is added successfully to the User keystore, and the next time they launch the app, they do NOT see this message again, however on windows 2008 R2 , this is not the case, the dialog is always displayed regardless if the check "Do not show this message..", and the certificate is being correctly added to the User keystore , I tried with standard/admin users, but got the same.
Any thoughts ?

I can run the app in the browser after clearing data, but if I then add it to the homescreen and attempt to relaunch from there, I get a plain page giving the following error:
Safari cannot open the page. The error was: "FetchEvent.respondWith received an error: Returned response is null."
Subsequent launches in the browser then also give that error. I have to again 'clear data' in the browser to get it to work again.
I'm using Workbox v3.6.2 (the latest, at the time of writing), and my iPhone is running iOS 12.
This looks suspicious, but it's a bit over my head (well, the workaround is anyway). It makes me want to try to down grade to iOS11.X again, and/or install Technology Preview 59.
I have this same problems. On iOS 12.0.0 work properly but after updating to version 12.0.1 I have this same error like you. I have test this same application but on two different devices (iPhone) with two different version of iOS.
Looks like there are multiple possible reasons for this error - I've had it twice ;
Occasion 1 : Needed to add a ROOT certificate and set it as Trusted on device.
my conditions;
I was getting the same error on an iPhone 5s with iOS 12 when loading pwapp from local server.
Using self signed certs on a development machine for server.
Not using Workbox.
Not getting problem if loading pwapp from provider hosted server with ssl cert from iOS recognised cert authority.
Turned out it was to do with security certs - (not using a mac so can't debug to the level of network/security issues on the device / direct to fully diagnose).
Fix was to ;
create a self signed root cert and use that for my server.
convert (copy of) root cert .pem file to .der
access .der via safari on the device / add profile, set as trusted.
(Correct way is to do root, intermediary and server certs , use the server cert and serve the root cert via url or email it to email client on device.)
useful links ;
see Getting cert in General->About->Certificate Trust Settings
Occasion 2 : Turns out you have to access the pwapp from the home screen icon at least once while you have access to the server.
To reproduce ;
(networking on)
delete icon from home screen and clear safari history and website data
visit the pwapp url
add to home screen but do not launch
turn off networking
attempt launch from home screen => get the error
turn on networking, launch pwapp from home screen => ok.
close pwapp, turn off networking, launch pwapp from home screen => ok.
So looks like an iOS/Safari/Webkit bug
I am using VM(Ubuntu server 1804) of Azure(Japan region).
How to reproduce:
Install xrdp, xfce4 using apt-get, and successfully login to the VM via Remote Desktop. After installed firefox, I installed Visual Studio Code, and installed Azoure Account Extention(0.4.3)
then tried to login to my azure account.
After click [OPEN] button on popped up dialog with message "To sign in, use web brower to open.... enter the code GPJXXXXX to authenticate.".
A borwser was opend (Firefox), and type the code , then clicked "Continue" botton.
Select the account listed in the dialog (Pick an account)
Type my e-mail address and my password.
Click "Sign in with your phone or token device"
Answer for the phone, and type pincode.
A browser was changed to new message "you have signed in to the Visual Studio Code applicaton on your device, you may close this weindow."
Start playing with VS code again, and try to select subscriptions (Azure: Select Subscriptions"),
VS code display Pop up dialog with following message.
"Not signed in , sign in first. (Source: Azure Account Extention)".
Is there any setting should I do to run VS code can on a Azure VM?
Try the following: File->Preferences->Settings, then click "Azure configuration" and add your Azure tenant id.
I´m trying to install a program in the windows mobile 6 emulator, running it as standalone image (PPC_USA.BIN). The program installs sucessfully, but when i try to run it, the error msg is:
The file '' cannot be opened. Either is not signed with a trusted certificate, or one of its components cannot be found. If the problem persists, try reinstalling or restoring the file.
Any suggestions?
The application probably requires that security be lowered. So to be able to run it, the device needs to have security lowered at least to the level at which the user is asked for permission when he/she is running an unsigned executable. In the context of Windows Mobile security, it means that the device's security configuration needs to be set to Two-Tier-Prompt, One-Tier-Prompt or Security-Off (see MSDN for more details).
Changing of the security configuration might require device manufacturer's or operator's assistance.
In some cases it can be done by the user. Some of them are listed below:
If the user has a registry editor application which can run on
the device and can change the device registry (such application
needs to be signed by a certificate which is trusted by the device
though, or the same issue will repeat itself.)
The device has installed Microsoft Windows Mobile development
certificates.
The device allows the user to install the Microsoft Windows
Mobile development certificates.
Of the above, 2 and 3 are more than likely be the case; if so then try the following:
Install Windows Mobile SDK (Here)
Install <WM SDK>/Tools/Security/SDK Development
Certificates/Certs.cab on the device.
Go to <WM SDK>/Tools/PocketPC/Security/Security Configuration and
use one of the cpf file to change the device's security
configuration (see the Readme File located at <WM
SDK>/Tools/PocketPC/Security/Security Configuration/ReadMe.txt)
Hope this helps someone, even-though I'm a year or so late...
I have a blackberry 10 webworks application by following this link ("https://developer.blackberry.com/htm...llo_world.html") . This application works fine and I have signed this app from command prompt using this command "blackberry-signer -storepass xxx path_to_bar file" and the application is signed successfully.
I got this message in Command line as " Info: bar signed"
But when I tried to verify my bar file by unzipping it i found an additional manifest.bbr file. when I package another blackberry 10 sample application in QNX momentics IDE , there is no such manifest.bbr file. Its getting signed perfectly.
Now, all I want is to port my Blackberry 10 webworks app from RippleSites folder to QNX momentics IDE and I want to sign the app from that IDE to get it signed perfectly.
How can I do this? can anyone help me on this?
If you've signed the app successfully via WebWorks then you're good to go. No need to question the "bar signed" output from the signer.
If you want to port your BlackBerry 10 app from web to native then you'll need to rewrite it using QML and possibly C++ depending on what features and/or APIs you're making use of.
I am testing my Windows 8 app by logging in as the guest account. I want to see how it works installing with limited permissions.
It seems I cannot debug any apps. Here are the steps:
Login as the Windows 8 Guest Account
Open Visual Studio.
Create a new Windows Store app, using the grid template
Click the play button to deploy to the simulator or the local machine.
Upon deployment, I receive this error:
Unable to debug Windows Store app App1/App1/bin/Debug/App1.exe
The debugger was unable to find the registration for the target application. If the problem persists, try uninstalling and then reinstalling the application.
Am I unable to deploy apps without being an administrator? If not, is there a way around this problem?
It doesn't make sense to try to debug installing an app as a guest. Guest accounts are not allowed to install apps. There is a short forum post regarding accounts here.
If you are wanting to see how the app performs for a guest after it has already been installed, you can run the app from the desktop tile, but I don't know how to run the debugger on it, or even if you can.
