I paid over $1200 for your apps but they are impossible to install.

And if you don't really like what I write, let Native Instruments give me direct links to what I paid for. I'm fine with that. It's very easy to do.

I found a very interesting installation method if you have a source from which you can take the content of already installed expansions.
You need to copy them to the content folder without changing the directory names and try to show where you have this extension using the specified button.

There is some chance that the expansions will be picked up and NA will recognize it as installed.
If this option does not work, then after copying the folder with the content to the content directory, click the install button, and it will install very quickly. I managed to install more than 30 expansions this way.
I wrote to support about the remaining 11. I really hope that they will send them to me.
