How to make IIS7 play nice with Office Interop

2012/11/102012/11/10

I’ve just started working on a new project for which we had to dig out one of our older libraries. We wrote it to retrieve data from MS Excel workbooks using the Office interop assemblies, and thus far it has never given us issues. A slight change this time round was that we were using our library in an ASP.NET site rather than a desktop application. As a result I was faced with two errors that we’d never seen before.

Error Message:

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0×80070005 (E_ACCESSDENIED)).

Solution:

This is a COM permissions problem.

Start > Run > dcomcnfg (or “mmc -32″ and then add the Component Services snap-in manually if you can’t find the app under step 3)
Navigate to Component Services > Computers > My Computer > DCOM Config
Locate the MS application giving you trouble (eg: “Microsoft Excel Application” for Excel or “Microsoft Word 97 – 2003 Document” for Word)
Right click > Properties
On the security tab: Select Customize under Launch and Activation Permissions and click Edit…
Add the account under which the site is running (eg: Network Service) and assign Local Launch & Local Activation permissions
Voila!

Error Message:

[COMException (0x800a03ec): Microsoft Excel cannot access the file '<filename>'. There are several possible reasons:
• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.

Solution:

This seems to be an issue with Excel/Word/etc not having access to a profile when being started via the interop route.

Open Windows Explorer
Depending on whether you installed a 32bit or 64bit version of office you will need to do one (or both) of the following:
1. 32bit Office installation: Navigate to C:\Windows\System32\config\systemprofile
2. 64bit Office installation: Navigate to C:\Windows\SysWOW64\config\systemprofile
Verify the folder "Desktop" exists (create it if it's not there)
Right click > Properties
On the security tab: Add the account under which the site is running (eg: Network Service) with default permissions (Read & execute; List folder contents; Read)
Voila!

Many thanks to the contributors of this discussion.

aspnet account dcom permisson for MS Word

2012/11/102012/11/10

Question to doc2any Converter Command Line,
https://www.verydoc.com/doc-to-any.html

I have a win 2000 webserver. Any thoughts on how to grant ASPNET account permission to run Microsoft Word using DCOM. I know this can be done using dcomcnfg but not sure what is the right way.I do not want to mess up a production server.

------------------------------------------------------------------------------
Under DCOM Config locate “Microsoft Word Application” right click on it and go to Properties.

Under the “Security” Tab, in the “Launch & Activation Permissions” select “Customize” and Click on Edit.

Give All Permissions to the following Account
      IUSR_<Machine_Name>
      IWAM_<Machine_Name>
      ASPNET

Now try your application.

If this does not work, then create a New Windows Account on the Server, say "Word_User" and put it in Admin Group, give it Admin Permissions. Alternatively use the existing Admin account (The account Admin uses to log into the Web Server Machine). Now add this account to the List above, i.e. in DCOMConfg give this account all permissions as well.

Now Impersonate using this account for you app. For this Modify your Web.Config and Add these Configurations

Where admin_user_account is the Login Account of Admin on the Server or the "Word_User" that you created on the Server with Admin Previlages.

Microsoft Excel Application entry missing in DCOMCNFG

2012/11/10

VeryDOC DOC to Any Converter Home Page,

https://www.verydoc.com/doc-to-any.html

Hi I'm using windows 7 home premium. I have an application in ASP.Net which uses Excel Application Object. It used to work fine in XP but in Windows 7 I'm getting an error as mentioned below:

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.

I need to give permissions to Microsoft Excel Application in DCOM config but I can't seem to find this in windows 7. It used to be there in earlier versions but now its not there. I tried to reinstall Office 2007 but still I couldn't find it in DCOM config. Please suggest where I can give permissions to MS Excel Application so that my application runs without errors.
----------------------------------------------------------------------
1. Control Panel -> Administrative Tools -> Component Services
2. Console Root -> Component Services -> Computers -> My Computer -> DCOM Config
3. Right-Click 'Microsoft Excel Application' and choose Properties
4. Click 'Security' tab
5. Customize 'Launch and Activation Permissions'
6. Add the local ASPNET user and give it all permissions

----------------------------------------------------------------------
Thanks for the reply.. the problem is that there is no "Microsoft Excel Application" in dcomcnfg.. I'm not able to find it there. I reinstalled Office 2007 also, but still I couldn't find it there.
----------------------------------------------------------------------
I have the same problem. I took a look in the registry to find the correct CLSID from the appID but I did not found anything. Is there any workaround or solution ?

Best regards
----------------------------------------------------------------------
I found a solution to this problem by giving permissions at system level by following the steps below
1. go to DCOMCNFG
2. In the left tree structure, right click on My Computer and select Properties
3. Click on COM SECURITY tab
4. Give Permissions to Network Service and Users in the "Access Permissions" and "Launch and Activation Permissions" by clicking the Edit Default buttons.

Now check your application.
----------------------------------------------------------------------
This does not fully work. Having changed the settings according to your solution, I could create excel reports (via asp.net, iis and office). however, a day later, this no longer worked although the permissions are still assigned to the network account (and the account of the iis pool). There must be another setting that affects using Office/Excel in IIS 7.5 on Windows Server 2008/Windows 7

Any help is appreciated
----------------------------------------------------------------------
Use MMC comexp.msc /32 on Windows 7 x64
----------------------------------------------------------------------
This solution is ...

- Windows 2008 Server x64
Please make this folder.
C:\Windows\SysWOW64\config\systemprofile\Desktop

- Windows 2008 Server x86
Please make this folder.
C:\Windows\System32\config\systemprofile\Desktop
----------------------------------------------------------------------

We faced similar kind of issues and found some workarounds ...

1. Issue in opening word document (from DCOM component, in windows 2008 64 bit machines)
create folder called "Desktop" under "C:\Windows\SysWOW64\config\systemprofile" or "C:\Windows\System32\config\systemprofile" as mentioned in http://social.msdn.microsoft.com/Forums/en/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91

2. Issue in printing
configure word to run as "Interactive user"

Steps to configure word to run as “Interactive User”
1. open registry editor (regedit)
2. Search for winword.exe, copy the AppId/Guid for word from “HKEY_CLASSES_ROOT\AppID\WINWORD.EXE”
3. Open Compent Services (dcomcnfg), Go to Computers->MyComputer->DCOM Cnfg
4. Select the application with the guid copied from registry.
5. Right click on it, select properties, select Identity tab, select “Interactive User”, click on “Apply” button.
