Reaper crashes on loading Arturia plugins

Whenever loading a Reaper project with an Arturia Synth VST, Reaper crashed.
Uninstalling everything and reinstalling didn’t help.
the problem persists.
When Reaper crashes, reopening causes Reaper to freeze.
Only restarting the PC helps.
This only happens with the Arturia Synths, not the FX.
All other plugins from other vendors work fine.

HI @MisterE

Sorry to hear this, have you also cross posted on The Reaper forums too as i’ve not heard this one before, not to say there might more people experiencing of course.

It would also be worth your while logging into your account to contact Arturia Support to see if they can be of help, they don’t work weekends though.

HTH!

Hi MisterE,

Is the crash a) before creating a new project (when loading Reaper) or b) when loading a project previously created and saved with Arturia VSTs?

I have been using Reaper for a few years in Linux and Windows 10 and 11.
I can’t remember having encountered this problem.

The only suggestion I would have is to check in the Preferences (Ctrl+P), if the the arturia vst path is properly set in Edit path list.

In case (b), maybe you can try disabling Scan new updated plug-ins on startup.

I’ve tried with Cantabile and had the same problems.
So it’s not just Reaper.
The paths are correct but the scan stops as soon as it tries to scan the Arturia synths./
But I’m glad to say I found a workaround.
i had to go into the properties of the synth exe files and set it to “open with Administrator rights”
That did the trick.
Still odd that I had to do this.

Hey @MisterE
Thanks for updating us.
UAC can be a MAJOR PITA at times, i’ve found.
Sometimes you have to ‘run as admin’, as in your current case, and sometimes it doesn’t seem to care.
I’ve not had this issue myself with any Arturia products, but have with one or two other companies, but even then, it seems to be rather inconsistent.

Great to see you’ve identified the issue though!

It is odd, MisterE.

As a Linux user for more than thirty years, no system is more demanding with rights (to read, write or execute).
As for Windows, I would check if you may have installed the Arturia collection or Reaper and Cantabile as Administrator.

I have not installed Reaper and Cantabile with Administrator rights.
But that was never a problem before.

What was strange though was that I had to install three plug-ins from Arturia manually.

By “manually”, I assume you mean one by one instead of in bulk, with the whole collection.
It happened to me also for a few plugins. I don’t remember the details.

I would rather suspect that Arturia VST Collection may have been installed with administrative privileges. It would explain why they can’t load with two different DAWs.
Maybe not. Maybe a UAC quirk as Mat puts it.
