Keeps asking me to install companion app even though I have already installed it.

[Sagun Pandey]

I am using this extension on the latest version of Chrome i.e. Version 83.0.4103.116 (Official Build) (64-bit)

I am using Windows 10.

For some reason, the extension keeps asking me to install a companion app while I already have 10 times. I am a paid member. Please help, this has started getting frustrating.

[jc vdh]

hi,

do you have other addons or blockers that might interfere? What you can try is to start a new clean Firefox profile (type about:profiles in the URL bar then enter) with only VDH to see if it works better.

I don't use Firefox, please suggest the solution for Chrome. I disabled all the extensions except Video DownloadHelper and it still isn't detecting companion app. Please provide a fix/solution, else a refund would be appreciated.

[Sagun Pandey]

I tried with Firefox as well. However, the companion app setting keeps showing "Verifying Companion App…" even though I have it installed.


Let's say we are somehow able to fix the issue on Firefox. How do we transfer my premium license from Chrome to Firefox?

I just want it to work, Chrome or Firefox, I don't exactly care. I am looking forward to your kind assistance.

[Sagun Pandey]

See the Chrome extension id, native messaging host path in the registry, and the specific config JSON in the companion app folder. Is anything wrong here?

sorry I don't know, I forwarded to the tech team.

Sagun, i notice you took a screenshot of the registry at location HKLM/SOFTWARE/Chromium/NativeMessagingHosts/net.downloadhelper.coapp . In your case, the registry key being used is HKLM/SOFTWARE/Google/Chrome/NativeMessagingHosts/net.downloadhelper.coapp

Anyway, you could try searching for "net.downloadhelper.coapp" in all the registry and remove the corresponding key. Also, remove the folder C:\Program Files\net.downloadhelper.coapp. Then reinstall the coapp the normal way. This will solve the most common issue where an aborted previous install interfere with the new install.

Also, you could try installing VDH on Firefox (you don't need a licence to do so). If it works on Firefox, it means the coapp is correctly installed (it is the same coapp for Chrome, Firefox and Edge) and the problem is around your Chrome setup.

[Sagun Pandey]

Thank you for your response. Here are a few things I tried:


This one here is when I tried installing the addon on Firefox.

As you can see the status keeps showing "Verifying Companion App...". I guess the issue is not solely with the Chrome extension.




I also tried clearing all the registries related to Video Downloadhelper, uninstalled the companion app, removed any remaining folders, removed the extension from the browsers, then started everything from scratch. Chrome is still asking me to install the companion app.



I don't know what I need to do next.

And here is the error on Chrome:

I have made so many attempt to get a response here. Please refund or help me fix the issue.

In the few related cases we had, the issue came from either failed previous installation attempts or conflicts with other software components like aggressive "anti-malware" applications.

Maybe the way to go is that we refund you. You can keep trying to clean-up your system and install the coapp (you can do so without the need for an active license). If you succeed, you may want to repurchase the license.

Please send the reference of the transaction so i can refund it.

Sorry for the burden.

[Sagun Pandey]

Thank you. Please refund.

This is happening with me too, but I'm not going to go through my registry and fuck up my computer trying to fix your issue.   I would like to have full access again because I like your app,(Firefox) but why can't you just give a new license to me?

Whatever old version of Firefox that isn't working with your new version of Video Downloader sounds like the problem.

I am up to date, can you send me a license that works with your up to date App?

[Paulie n. SD]

I think my question got lost in the queue.

Are you saying possibly a failed installation video downloadhelper?

Can I uninstall/reinstall the app? Would that resolve the issue.

Again, I use the application frequently at home and don't mind multiple licenses, if need be.

But I'd like to use the application without the companion app.

Previously it gave me an "either/or" option and I always selected the option to use Firefox for the downloads.

This is a new computer (my company traded my laptop out for a MS Surface 3.

Thanks,

Did you see my answer from yesterday ? https://groups.google.com/d/msg/video-downloadhelper-q-and-a/9Rwa5P1km98/rbS4WMAUAAAJ

Same problem. Latest Firefox, latest Mac OS.

I've installed the companion app (from DMG) and run it. I've then quit and restarted Firefox, but VDH still claims that the companion app isn't installed.

I have admin rights on the machine.

[Kasimir]

Hi,

I have the same problem.

The companion app is installed, but the issue might be the naming.

In the applications folder the name is  net.downloadhelper.coapp.app and not net.downloadhelper.coapp that this sw might be looking for.

There seems to be no way of changing the name of the compaion app or better said removing the .app from the end.

Any suggestions?

Well, they're at it again. A lot of people  had this problem a few months back. I operate Firefox and VDH stopped working yesterday. Last time I just waited it out and after  a week everything was back to normal. It is annoying but I have complete faith in the VDH techs. I believe last time the reason was Google was blocking any downloading ability but don't quote me on that. Thanks for listening.

[jc vdh]

thanks for the feedback, I forward to the tech team.

If your system (Mac or Windows) says it does not find the coapp, it is worth making a quick test using Chrome instead of Firefox (or using Firefox instead of Chrome). Both VDH versions (Firefox and Chrome) use the same coapp, so if it works on one browser and not the other, we got a useful information to understand the issue.

One possible cause for VDH to fail recognizing the coapp could be this scenario:

- you downloaded the coapp DMG

- you install it in user mode

- the manifest files are written in ~/Library/Application Support/Google/Chrome/NativeMessagingHosts/net.downloadhelper.coapp.json and ~/Library/Application Support/Mozilla/NativeMessagingHosts/net.downloadhelper.coapp.json, pointing to a user version of the coapp

- you change your mind, remove the user coapp binary files, reinstall the DMG globally as superuser

This won't work because Firefox (and Chrome) will still see the manifest files in ~/Library/Application Support/*/net.downloadhelper.coapp.json but pointing to a non-existent location (the place where the user copy of the coapp used to be). You need to remove those user-level manifest files for the system to work.
