My program works correctly within the visual studio. Outside, displays a COM error (System.Runtime.InteropServices.COMException (0x80004005): HRESULT error E_FAIL)

Question

My program uses adobe reader dll to display pdf within a form. In visual studio the program works correctly, but when I run it out of vs 2019 it presents an error. I believe it's some missing reference.

OBS: before the project was in version 4.7.2 of .net. I've updated the entire program to 4.8. Maybe this caused some mismatch? Incompatibility that does not exist when running the program direct by vs.

PDFView_Load:

private void PDFView_Load(object sender, EventArgs e)
        {
            try
            {
                PDFViewObj.src = @"C:\Biblioteca Fácil\tempPDF.pdf"; //this file is created by other class
            }
            catch(COMException)
            {
                //Recovery options here
                Error = true;
                this.Close();
            }        
        }

This is my Exception that just occurs if executed outside the vs 2019:

System.Runtime.InteropServices.COMException (0x80004005): Erro HRESULT E_FAIL was returned from a call to the COM component.

Hello @Manoel Victor ,

Welcome to Microsoft Q&A forum.

Perhaps you can try to Publish your project. Right-click your project > Publish and follow the Publish wizard. You can also change some settings(add some files) of publish from right-clicking your project > Properties > Publish > (optional) Install Mode and Settings > (optional) Application Files…

Best Regards,
Tianyu
