I have a QWebEngineView instance included in my .Ui file. Program compiles without issues. However, when I start the program (via Visual Studio Debug mode), following error pops up.
Could not find QtWebEngineProcessd.exe.
Note: In a different windows pc - this programs runs without any issues. Can someone please point me to the right direction?
There was a problem with the QtCored.dll What I had in the Debug folder was apparently different than the version installed in the workstation. Hence, application runs with a version different to what it was built with.

I build static Qt 5.10.1 with mingw32.
Ref: https://github.com/arkceajin/QtDemos/blob/master/windows-build-qt-static/windows-build-qt-static.ps1
For testing purpose, build an empty QML project, it could run perfectly in QtCreator.
But if I copy the release build to another Win10&7 PC which doesn't contain the Qt environment, it will crash after the windows appeared. I'm guessing something missed inside QML.
Update:
I found No qmlscene installed appears in the Qt Versions tab, not sure it relates to the issue or not.
These two files did generate in the build folder.
projectname_plugin_import.cpp
projectname_qml_plugin_import.cpp
Found the similar issue: https://forum.qt.io/topic/42145/i-can-t-run-static-qt-qml-app-on-another-computer
Update 2:
Problem solved but I want to know why.
Here is I tried:
Connect a Win PC using remote desktop from another Win PC, run a static build QML program, then it crashed immediately after the Window appeared.
Directly login into the same local machine, run the same static build QML program, successful run.
Using the remote desktop run dynamic link QML program with Qt libs, successful run.
So the problem is Windows remote desktop, but I can't find the doc or bug report about it, if you have any idea or guessing, please help me.
I want to deploy my QT program and I can't find the reason it doesn't work, maybe you guys can help me ?
I work with visual studio 2010, windows 7, QT 5.0.2.
I have tested my deployment tree on my own computer and it works fine.
When deploying my application I ship every necessary dll that I am aware of. Depends.exe does not complain. I also deployed the plugin I know of, and since it still did not work I moved my entire plugin folder in the exe folder.
When I execute it on any other computer than my development computer, the program exits instantaneously with no message whatsoever.
Any idea where I should look now ?
How can I debug that kind of issue ?
Did you try deploying the debug version of the program and then starting it from the command line. The debug version will output more information to the console which could help you resolve the issue.
You will have to also deploy the debug versions of the MS c-runtime libraries.
Deploying the debug version is not a permanent solution, so you should not adopt that as normal routine for distributing your software. I am just suggesting that you try running the debug version one time on that particular machine until you figure out the issue. Then remove the installed program and install the release version again.
You can run your application using QtCreator:
Debug > Start Debugging > Start and Debug External Application...
This can give you more information about what's going on.
I am trying to debug my production website using the code on my local system.
I am using VS2010, and tried all sorts of things still didn't work.
I tried using VS Development Server, and tried using IIS still didn't work.
When I attach the process debugger starts but break points were not hitting.
I tried attaching process to W3wp process, and tried attaching it to IE also.
Still its not hitting break points. Any idea whats causing this.
Thanks
What you want to do is called "Remote Debugging".
Here is an MSDN link to get you started: MSDN
Try clearing the settings of Visual Studio
Tools->Import and Export Settings Wizard->Reset all settings->No…->next and set it
One more option, which worked for me is to open the VS in Safe Mode. It will 100% work:
Open Windows Explorer, and navigate to \Common7\IDE;
Devenv /SafeMode: Launches the IDE in safe mode loading minimal windows.
Hoping that I do this corectly.
I am having the above issue. My development machine is win7 64. Im developing x86 application,(x86 set in compile options). I have downloaded sqlite-netFx40-setup-bundle-x86-2010-1.0.81.0 as my app will be on .net4. I have referenced the above dll, set it to copy local. Can confirm that its in the deployed dirrectory. Tests OK on development machine both as a debug and a fully instaled app. When I put the app on a separate win 7 64bit it wount run due to the Dll. It installs ok into ProgramFiles(x86) and runs untill the database is required. The dll is in the instaled dirrectory when instaled on the other PC. (fresh win instal).
I am using InstalShield and it is also telling me about an error ' -6248: Could not find dependent file system.data.sqlite.dll, or one of its dependencies of component' but it compiles OK.
Im stearing at the Dll in the program , in the references, the intelisence picksup the SQLite name and all the code is right. I have referenced by browse and then finding the dll.
What on earth could I be doing wrong ?
This has had so many views that I decided to answer this so as to help others.
The problem isnt a big deal once you know what it is, despite the error message that sends you almost in the wrong dirrection. The problem isnt the DLL, its one of its dependancies. Basicaly you have to install C++ distributable file on the client machine , even if you are using VB.net. I cant take credit for the find, it comes from here http://justanothersoftwareengineer.blogspot.com.au/2011/08/how-to-make-systemdatasqlitedll-work-on.html.
I am running Visual Studio Ultimate on Windows 7. Here is the description of my problem:
My VS 2010 had been running absolutely fine until today when it started giving error "External Component has thrown an exception" when I try to open a new website. Creating a new web application works fine though but I am unable to run any of them.
While trying to run the previously created websites/webapps, its giving error as "Unable to launch ASP.NET development server".
And when I try to debug the website/web app, I am getting error: "Unable to launch ASP.NET development server. An attempt was made to perform an initialization operation when initialization has already been completed".
Similar errors are coming when I try to open Windows Form Applications and other projects.
No errors are getting logged on event viewer and I cannot see any other error information apart from what is mentioned above.
I searched all over internet but no help. I have already trying un-installing VS2010 using the script at this link (provided by MS). But when I re-install VS2010, it still shows me same error. To my surprise, after re-installing VS still shows the previous project list in "Recent Projects". I really doubt if VS is getting uninstalled.
I am totally clueless and any help would be highly appreciated. I am left with no other option but to format my OS if I don't find a solution here :( Please do let me know if any other details are required...
It might be caused by an adding or extension that you've installed, maybe without being aware of.
there are several ways to deal with that - one is to get inside add in manager and remove/ deactivate them.
if VS can't load there is a flag that should do the trick.
check this link for instructions on devenv flags.
you can use: /ResetAddin or /SafeMode
