[build/debug] Command failed - postbuild-win.bat

I am getting this error trying to build the midi effect vst3 on windows:

Severity	Code	Description	Project	File	Line	Suppression State

I would really appreciate some help as I am a total newbie with both iPlug2 and Visual Studio/Windows coding. Thanks in advance

Can I get some help on this one?
I haven’t been able to do anything with iPlug2 yet

VST folder write privileges?
Check if the plugin exists in the Build folder in your project folder.

Discord iPlug2 is a bit more alive than this forum.

Yeah it looks like the post build script is failing since it can’t write to the "C:\Program Files\Common Files\VST3" folder


Yes, finally it builds! Thank you guys.
I’ll get on the discord then
