Sharing .vst3 files

Hey, I am completly new to this topic and hope someone is able to help me. I downloaded the vst3sdk and build it. Now I try to share it with a friend but if i take the .vst3 file and send it to him, but his DAW wont find the Plugin. On my Computer its no Problem.
Thanks in advance!!

did you check the location of the VST3 plug-in?:
Plug-in Locations - VST 3 Developer Portal (

Yes i did and we put the vst file under C:\Program Files\Common Files\VST3 but the DAW wont find it, my friend is a sound enginner and asked me if i could help him with writting Plugins, cause i am able to code. he doesnt get the sdk but said til now it wasnt a Problem and he doesnt needed the sdk to use other vst plugins. am i doing something wrong with the licensing?

This is not a licensing issue. It’s hard to say why your friend is not able to use your plugin.
A few things to check:

  1. Do you build for the same architecture your friend’s host is using (x86 vs x86_64)?
  2. Did you build a release version?
  3. Did you copy the while vst3 folder and did your friend copied the whole vst3 folder to the correct location?
  4. Does the host your friend uses support VST3?
