PB with external plugin in audacity

Hi,
On to my Windows 10 PC I’ve just the latest version of Audacity, that means 2.3.3 and i’ve also installed the Accusonus ERA De-Reverb plugin.

Along with these installations, i’ve also installed the good version of ffmpeg for the compatibility with Audacity 2.3.3

So, when i want to use the external plugin onto an audio sequence, Audacity abort and i get a log about some problems.

And i don’t know what is the problem and how to solve it.

Here is the log :

19:49:24: Audacity 2.3.3

Tanks a lot if someone can help me.

So, when i want to use the external plugin onto an audio sequence,

The Deverb plug-in, right?

Did you install the 32-bit version? (Audacity is a 32-bit application.)

I found some information on the [u]ERA website that might be helpful.[/u]. It does claim to be compatible with Audacity. (It says to use Audacity 2.2.2, but 2.3.3 will probably work the same.)

Hi,
Yes indeed, I proceeded exactly as indicated in the Accusonus documentation. But it doesn’t work on my ASUS laptop.

In addition, I also installed Accusonus ERA bundle on my desktop PC (which I assembled myself) and I was able to use the plugin without any problem. It is also equipped with Windows 10, but with a graphics card other than that integrated into the motherboard, and a SoundBlaster sound card.
I may be thinking of a driver mismatch, but I’m not sure.
