Manifest helper failing

General JUCE discussion

Hello all,

I’m getting an issue when trying to build my vst3 plugin in vs2022. I seem to be getting a manifest helper failed error, but I’m not sure what the error is pointing to or what I should do to fix this.
If anyone is able to help me, I’d appreciate it! Here’s the error:

That looks a bit suspicious, I wonder where that extra slash is coming from.

Are you able to build any of the example VST3 plugins successfully?

Hi, I actually managed to get this one figured out in the end! I’m using some libraries for the plugin it seems, and they needed to be installed in the helper folder for it to work properly.
