AddinManager Error - AddinManager.CAddinManager cannot be found in the addin-Assembly.

Hi all, I seem to keep on having errors with the add-in manager. I got it working for the first time a week or so ago and I was able to bring up the dialog but now it's not working and is getting stuck.

tbh, it'd be kinda nice if the code for the add-in manager was open source so we could go through and debug the errors we have with it. or maybe it's just me having this many problems with it.

The goal is to get this running for Revit 2018 - 2021 ideally... or even just one of them.

I am getting this error:

here are the files I have which came from one of my previous posts:

here is the .addin file

<?xml version="1.0" encoding="utf-8"?> <RevitAddIns> <AddIn Type="Command"> <Assembly>AddInManager.dll</Assembly> <ClientId>8C0A9E25-B7C5-421c-A1AB-702F73FA551F</ClientId> <FullClassName>AddInManager.CAddInManager</FullClassName> <Text>Add-In Manager (Manual Mode)</Text> <VisibilityMode>AlwaysVisible</VisibilityMode> <LanguageType>Unknown</LanguageType> <VendorId>ADSK</VendorId> <VendorDescription>Autodesk, www.autodesk.com</VendorDescription> </AddIn> <AddIn Type="Command"> <Assembly>AddInManager.dll</Assembly> <ClientId>6FDB8EC7-CCD3-4fc0-ADB7-B459D298FB93</ClientId> <FullClassName>AddInManager.CAddInManagerFaceless</FullClassName> <Text>Add-In Manager (Manual Mode, Faceless)</Text> <VisibilityMode>AlwaysVisible</VisibilityMode> <LanguageType>Unknown</LanguageType> <VendorId>ADSK</VendorId> <VendorDescription>Autodesk, www.autodesk.com</VendorDescription> </AddIn> <AddIn Type="Command"> <Assembly>AddInManager.dll</Assembly> <ClientId>91A2419C-5FCA-491A-BAA3-29A497EC07C7</ClientId> <FullClassName>AddInManager.CAddInManagerReadOnly</FullClassName> <Text>Add-In Manager (ReadOnly Mode)</Text> <VisibilityMode>AlwaysVisible</VisibilityMode> <LanguageType>Unknown</LanguageType> <VendorId>ADSK</VendorId> <VendorDescription>Autodesk, www.autodesk.com</VendorDescription> </AddIn> </RevitAddIns>

Any and all help in resolving this is appreciated. It'd be nice to not have to restart Revit to debug for a change.

Hey,

Your files and the .addin file look good. I´ve attached the files I have on my computer, you could try with them, maybe it is a problem with that specific dll, which would be weird.

What path and what Revit version are you using? does it fail in all Revit versions?

I hope it helps,

Kind regards.

I have created an executable to install all the versions of the AddInManeger on the computer.

https://github.com/ricaun/RevitAddInManagerCollection

I already update the version Revit 2022 is ready.

See yaa!

once I replaced the files, it started working again. I'm not sure what happened.

Thanks again for sharing the files.
