An exception occurred when instantiating a COM object.

Report · Jan 05, 2014

Hi,

We are testing CF 10 on 2012 R2 with an old CF application. I understand COM objects only work with 32 bit CF, so I have installed the 32 bit version, but I am receiving the following error:

An exception occurred when instantiating a COM object.
The cause of this exception was that: AutomationException: 0x80040154 - Class not registered.

I found this old article mentioning to register typeviewer.dll - http://helpx.adobe.com/coldfusion/kb/coldfusion-mx-class-registered-error.html but I am unable to locate this dll anywhere.

Is anyone able to provide advice on how to resolve this issue.

Thanks

Elise

Have managed to fix the issue by copying the typeviewer.dll file from a CF 8 install and register it on the server.

Any chance that there is a newer version of typeviewer.dll out there and if Adobe could send a copy of it to me?

Thanks

Elise

Hello Elise,

Since the server itself is 64-bit, you may try the suggestions mentioned at http://forums.adobe.com/message/5975449#5975449 for CF10.

Hope this helps.
