Problem after installing HS and FCPX 10.4

Hi every one,

I am installing for a friend FCP 10.4. He did have on his 17" MBP i7 16 GB 1 TB SSD Sierra and FCP 10.3.4
Now I have installed it on his MacPro (MacPro from El Capitan) without a problem, but on his MBP from Sierra to High Sierra. and now FCPx is crashing al the time.
What I have done is remove preference no go, remove app and install it again nog no, search for com.apple.proapps.xdcam.radplugin no go. Even in the FCP X app I could not find it.
Removed all the FCP 7 stuff with FCP remover
Removed all XDCAM software, no go.
On this momentI reinstalled again H S. And I am waiting for this.

I searched on the internet but could not find any problem.
There should be a folder in the library for ProApps but is is not there could that be the problem. (main and user lib)

I hope not but perhaps a whole new fresh install is needed.

Remove FCPX using FCS Remover. That will get absolutely everything you need to remove. Reboot, reinstall.

What "percentage" of that internal drive is free space?

What 3rd party plugins/addons are installed?

After the new OS ( installed over the other`0 search for hidden files no go
I followed the steps and now removed als FCPX with FCS remover.

Installed , started and crashed again

Plugins are Coremelt (Updated to the latest, Latest Neat video, Color Finale

Strange strange, after aI send last message, restarted again FCP 10.4 and it works. Just like 'windows' ehn?? :ohmy:

But thanks any way

No, not just like Windows, cause once that breaks, you can't fix it...
