Whenever I try I just get this error:

VDH version: 7.6.0

companion app version: 1.6.3

operating system: Ubuntu

Browser: Firefox 92

I'm running Windows 7 64-bit, Firefox 92.0.1 64-bit, licensed VDH 7.6.3a1 beta, CoApp
1.6.3. It downloaded fine for me. One thing I did do was change the resolution to
1920x1080, what YouTube labels as 1080p. Maybe that makes a difference. When I did
that, the entry in the VDH menu said simply 38MB. That's it. No title, no duration, no
resolution, no file type. Just the file size. I should have taken a screenshot. Oops.
I've just gone back to the page to see if I could duplicate that result but now, VDH is
showing me a proper variant with a title, resolution, etc. Weird. But then, YouTube is
weird. Anyway, it worked for me. Try changing the resolution & see if that makes it
work.

From a VDH user (not staff):

Heh - the dreaded glibc problem we had for so long!

Look for alternate versions here:
https://www.downloadhelper.net/install-coapp?browser=firefox#other-installers
Look for "Other system installers" in the list at bottom-left.

From a previous "conversation":

I Went to:
https://www.downloadhelper.net/install-coapp?browser=firefox
and under "Other system installers" had to expand the image (Ctrl-+)
to see the small, gray-on-gray "glibc: 2.31", and found the one
that said "glibc: 2.23" since my opensuse LEAP 15.2 uses glibc 2.26.

"Extra step required to complete install" brought the install scripts
as intended - and that's where I went wrong.

"Ctrl-+" expanded the scripts but not the dark, gray bars, and
"Ctrl-C" only copied what was visible in the bars, meaning all but
the rightmost last few words of the script, the "install --system" part,
which made linux think I was looking for a directory.

So when I figured that out and "did it right", meaning shrink (Ctrl--)
until the whole install-string was visible and would copy, I have since
downloaded and converted a video using VDH for the first time since
mig's "upgrade" to Ubuntu with the "upgraded" glibc -- HOORAY! IT WORKS!

So indeed the answer to the glibc problem is solved - the OS you're
working with MUST have a newer version of glibc than the version in
the coapp, period, full stop.  If you're on linux, and your glibc
version is lower than the one the coapp is built on, it won't work.

Good luck!  This program CAN be made to work....

alright. so I uninstalled the companion app and reinstalled another version of it with a lower version of glibc in it (the 2.27 version) and it works. it was a version compatibility issue.

Thanks for the help.
