There's one more issue you might need to address if you are using the Windows 2008 Server with IIS7. The server might report the following error:

Microsoft Office Excel cannot access the file 'c:\temp\test.xls'. There are several possible reasons:

<ul>
<li>The file name or path does not exist.</li>
<li>The file is being used by another program.</li>
<li>The workbook you are trying to save has the same name as a currently open workbook.</li>
</ul>

The solution is posted here (look for the text posted by user Ogawa): <a href="http://social.msdn.microsoft.com/Forums/en-US/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91?prof=required" rel="noreferrer">http://social.msdn.microsoft.com/Forums/en-US/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91?prof=required</a>

In case it helps somebody: 

I am running Windows 7 64-bit and I wanted to register a 32-bit dll. 

First I tried: regsvr32 and got the following error: 

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {A1D59B81-C868-4F66-B58F-AC94A4A7982E} failed due to the following error: 80040154. 

Then I tried to add the application through the Component Services (Run->DCCOMCNFG) (<a href="http://www.justskins.com/forums/difference-registering-dll-using-regsvr32-and-component-services-17280.html" rel="nofollow noreferrer">http://www.justskins.com/forums/difference-registering-dll-using-regsvr32-and-component-services-17280.html</a>) and got the following error:

There are many links to solving it but what worked for me was: 
Console Root -> Component Services -> Computers -> My Computer -> COM+ Applications -> your_application_name -> Properties: Security tab: Authorization: Uncheck 'Enforce access checks for this application'. 

I don't know what it does.

4.In launch and Activation Permissions, click Edit Defaults and add iis apppool\myapp to it and give it Local launch and Local Activation permission. Do the same for iis apppool\myapp.

<li>Select “Microsoft Office Word 97 – 2003 document”/”Microsoft Excel Application” and go to its properties.</li>
<li>In "Security" tab set “Launch and Activation Permissions” need to be Customize (Authorized user).</li>
<li>Now go to IIS and select application pool of the Web and go to its Advanced Settings and select “NETWORK SERVICE” as identity user.</li>
</ol>

I'm getting this same error when trying to export a csv file from Act! to Excel. One workaround I found was to run Act! as an administrator.
That tells me this is probably some sort of permission issue but none of the previous answers here solved the problem.

Maybe this workaround will help someone until a better solution is found.
