4K Video Downloader and Win 10 (v. 1909)

[jgg]

I can't get any version of 4K Video Downloader to work on my Win 10 Pro x64 (v. 1909) machine.

It works fine (including the latest update to 4.13.2) on Win 7; I've been using it with no problem for over a year.

My Win 10 Pro x64 machine is an Intel NUC 8i3BEH (Intel i3-8109U) with 8gb RAM, a Samsung 970 Evo Plus M.2 SSD (500gb), and Intel Iris Plus 655 graphics. The monitor is an Eizo Foris FS FS2333.

I've tried the .msi installer and the zip versions, 64 and 32 bit, of the latest and several earlier versions. The result is always the same: The installation doesn't indicate any problem. However, when I try to launch the program, either through the desktop icon or clicking the .exe file in the installation folder, nothing happens; the program simply doesn't open.

On the NUC I have Norton Security, MalwareBytes, and Windows Defender. I've added the program to Norton's firewall rules, but that didn't change anything, and, so far, I haven't been able to get to the point where I can even test whether downloading is possible: as I've written, it simply doesn't open.

What I find strange is that the program "Process Explorer" seems to indicate that the program is running!

Does anyone have an idea what the problem might be? I've searched but haven't found anything on the web that looks similar, so I guess it must be my machine, but I can't begin to guess where the problem might lie.

Thanks in advance for any assistance.

Try the compatibility mode. Right click on the executable, properties, set compatibility to Windows 7

Thanks very much for your reply.

I tried compatibility mode as you suggested, but it didn't fix the problem.

The good news is that I've found an alternative. It's called 3DYouTube Downloader, and it worked right "out of the box".

My plan is to stick with 4K Video Downloader on my Win 7 machines and use the other one on Win 10.

As far as I'm concerned, this case is closed.

I have exactly the same Problem with the current Version of 4K Video Downloader on my PC with Windows 10.

After Installation, I start the Program, but it is not displayed to me.

According to the Task Manager, it should be running.

I have also tried all the Compatibility Settings, but nothing helps.

Does anyone here have an Idea why it might not be running properly ?

Delete this folder:
C:\Users\XXX\AppData\Local\4kdownload.com
(where XXX is your user name on Windows)
and restart the programm.
It takes some time to start and connects to its homepage.

Thanks for the Tip, but unfortunately this only worked once.

Now the Program cannot be opened again, even if I delete the AppData Folder first.

Uninstall it with revouninstaller (free version) to remove all hidden tracks and files of the program.
Then download the portable version here in the software section.

reinstall the last version that ran.

I have now completely uninstalled the Program with Revo Uninstaller and reinstalled it.

Now the 4K Video Downloader starts normally again.

Thanks for the Tip about the AppData Folder.
