Guess: you are trying to write to File.DirApp and it fails because it is a restricted folder.
You should use XUI.DefaultFolder instead.

Thanks Erel I believe you are correct. I did have File.DirApp. I made the switch, but now I'm trying to find out why I have an error

Unknown type: b4xmainpage<br />Are you missing a library reference?

You should add a reference to XUI, not B4XPages. B4XPages projects have a specific structure.

So the install works now, but I'm still doing something wrong. The csv file never seems to get created, or if it is created doesn't go to the correct directory. There are no errors or messages in the debug.

In the AppStart sub I did

B4X:

xui.SetDataFolder("CACtrax")

and for the CSV save where I want the file to go to the same CACtrax folder I have

B4X:

Sub btnExport_Click
    Dim su As StringUtils
    Dim List1 As List
    Dim csvname As String = "Attendance.csv"
    
    List1=DBUtils.ExecuteMemoryTable(sql1, "SELECT * FROM PEOPLE",Null,0)
    su.SaveCSV(xui.DefaultFolder, csvname, ",",List1)
End Sub

Thanks, but I'm not sure where that is supposed to go. I've put in in multiple places, but the CSV file still isn't showing.

B4X:

Log(xui.DefaultFolder)

It turns out I just wasn't thinking clearly. The CSV file is being created. It is going to an AppData/Roaming directory. I was looking for the file in the install directory.
