First, I need to clarify that this is NOT a VBA related question. This error is occurring on a release program of Visual Basic 6.0 that has nothing to do with MS Office.
The program in question consists of an executable called "Color_Picker.exe" and an ActiveX control called "ColorManagementControls.ocx". I am trying to make use of Registration-Free Activation of COM.
Whenever I try to run my program with the manifests setup
"Application-defined error or user-defined error."
pops up. From the title of the error window, which is always the name of the offending class, I can tell the error is happening within the OCX.
The issue is that I know class runs free of error. In order to make sure this wasn't an issue of incompatibility with Windows 10, since the program is being compiled in Windows XP, I properly registered my OCX, and when I do that the program runs smoothly. So I'm guessing that my OCX manifest is not properly set up or requires extra add-ons because I followed the MSDN tutorial to the letter.
EDIT: I forgot mentioning that this had previously worked when I tested it with an unfinished version of both the program and class. I then added some properties to the OCX and made some UI improvements to the EXE. That is when it stopped working.
This is the EXE manifest being used:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1"
manifestVersion="1.0">
<assemblyIdentity
type = "win32"

<dependency>
<dependentAssembly>
<assemblyIdentity
