I can't find any solution to this problem. I can register the add-in from the Delphi XE8 IDE, but I can't deploy it to others. The Inno Script installer unpacks the contents correctly, but the COM will not load.

I get this error message when I try to use RegSvr32 to install my excel add-in:

"The module "C:\Program Files (x86)\ExcSimBasic\ExcSimBasicPrj.dll" was loaded but the call to DllRegisterServer failed with error code 0x80004005."

Any ideas?

Hello Michael,

0x80004005 is about permissions. I suppose you register a per-machine add-in. If so, you need to do this from an elevated command prompt.

In elevated mode I get almost the same error (in slightly different words):

Do you build the DLL for the 32bit or 64bit platform? Since it is deployed to Program Files (x86), it should be a 32bit DLL. Is this the case?

Yes, it is for 32bit but have also generated a 64bit version in the same iss installer: 


Source: "ExcSimBasicPrj.dll";          DestDir: "{app}"; Flags: regserver; Check: not IsOffice64
Source: "Win64ExcSimBasicPrj.dll";    DestDir: "{app}"; Flags: regserver; Check: IsOffice64


When using the command prompt (regsvr32.exe) I have tried to register the 32bit version since that is what I am using. The strange thing is that it registers nicely from the Delphi IDE.

Michael,

What parameters do you pass to regsvr32.exe?

%systemroot%\System32\regsvr32.exe /i "C:\Program Files (x86)\ExcSimBasic\ExcSimBasicPrj.dll"

You need to omit the /i switch.

Great. That solved the error message. But the COM still doesn't load in Excel.

Hello Michael,

Try to debug how the add-in module is constructed and how it processes the AddinInitialize, AddinStartUpComplete, OnRibbonBeforeCreate, and OnRibbonBeforeLoad event.
