Title: Icarus 3 - shared resources?
Post by: Examigan on January 24, 2026, 02:52:49 PM
I also sent email to your support about this, but then I thought I could just mention it here.

The way I understand it, there are shared resources between the VST2 and VST3.

I checked the secondary drive - D: that I have on my PC, and the VST2 shows there with the data files, etc. 
I looked at the C drive where stuff ends up for VST3, and it seems to be the same file size there.  So the data is doubled. 

That may be because I installed the VST3 later on, after I installed using the minimal only-VST2 option?

Maybe it would be better if when you install it the way I did (one at first, and then the other later), that it would check the paths to see if it's already there on either drive (if it really is supposed to share resources).

Or maybe that's how it is even when you choose the option to install both at once? VST2 and VST3.
But then, that's not sharing resources as I understand it at least; since it's doubling up that data size.

What's weird is under my list of apps, it shows only the amount of data for one install of Icarus 3 (0.99GB).
I thought it might show twice the amount of the file size, since it's in two places at the same time.

Thanks for any help!


Cheers,
Rob

Hello Rob,

Please do not send duplicate support requests to us as this creates confusion and additional workload.

There should be no data doubled unless you accidently did multiple installations to different directories or you  manually moved around data on your harddisc(s).

If this is the case you can fix it this way:
1) Uninstall Icarus
2) Delete all remaining Icarus_data, Icarus_sounds and Icarus_wavetables directories
3) Install Icarus.

Technical details:
All plugin versions (VST/VST3/AudiUnit) share the Icarus_data directory, the Icarus_wavetables and the Icarus_sounds directory. This saves up to 66% hardisc space. These directories are created within your installation path.
Further there are also graphics an DSP code shared. IcarusX64.dll contains all images for the graphics and most of the DSP code. This saves further 35 MB of discscpace on PC and 70 MB of discspace on the Mac.
A further advantage is that mainteance and testing for bugs is more easy.

Best Regards,
Markus
