Registering COM Object on Windows 64-bit For Use In Excel-32 Bit Is Failing

I have an Excel application that uses a COM object.

The COM object is VB.net and compiled in Visual Studio targeted to "Any CPU".

I am registering the COM object for the current user only. My NSIS installer does the following:

  1. NSIS runs Regasm and outputs a reg file.

  2. NSIS replaces all instances of "[HKEY_CLASSES_ROOT" with "[HKEY_CURRENT_USER\Software\Classes" in the reg file.

  3. NSIS executes the reg file and all the appropriate registry entries are created.

This works fine on:

Windows 10 64-bit / Excel 64-bit

Windows 10 32-bit / Excel 32-bit

However, I am hitting an error with:

Windows 10 64-bit / Excel 32-bit

For Windows 10 64-bit / Excel 32-bit my understanding is I must replace "[HKEY_CLASSES_ROOT" with "[HKEY_CURRENT_USER\SOFTWARE\Classes\WOW6432Node"

I am doing this in NSIS but Excel 32-bit is raising the error "Cannot create ActiveX component."

I tried replacing "[HKEY_CLASSES_ROOT" with "[HKEY_CURRENT_USER\SOFTWARE\Classes" but then Excel raises the error "Class not registered."

If I change the reg file to simply use "[HKEY_CLASSES_ROOT" (and forget about the registering for the current user) Excel 32-bit can the instantiate the COM object fine.

The problem is I want to register the COM object for the current user only.

What registry path should I be using that will be for the current user but Excel 32-bit on a Windows 64-bit can instantiate it?

Here is the reg file that is failing where "[HKEY_CLASSES_ROOT" has been replaced with "[HKEY_CURRENT_USER\SOFTWARE\Classes\WOW6432Node":

And here is the reg file that registers to [HKEY_CLASSES_ROOT] for all users. Strangely, if I do TWO reg file imports:

  1. A reg file import to [HKEY_CURRENT_USER\SOFTWARE\Classes\WOW6432Node

and

  1. A second reg file import to "[HKEY_CLASSES_ROOT"

then the COM objects are able to instantiate on Windows 64-bit in Excel 32-bit.

I have to import both to "[HKEY_CLASSES_ROOT" and "[HKEY_CURRENT_USER\SOFTWARE\Classes\WOW6432Node" for it to work.

I need to understand what is going on here and what the correct approach is.

Here is the reg file that imports to "[HKEY_CLASSES_ROOT":

Solution

  • I tried Albert's suggestion of making sure my NSIS installer was using RegAsm.exe in the 64-bit path at:

    C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe

    However, I compared the reg file created by the 64-bit RegAsm to the reg file created by the 32-bit Regasm and they were identical.

    I then realized that on Windows 64-bit registering a COM object for Excel-32 bit that I had to make sure the reg file was imported into the 32-bit view of the registry and not the 64-bit view.

    I accomplished this by using the following command in my NSIS installer:

    SetRegView 32

    This did the trick and the COM object was now recognized by Excel 32-bit.
