Run Huge ASP upload on 64 bit edition of OS (Windows 2003 64 bit, Win 2008) Article

Huge ASP upload and Script Utilities library is a 32 bit DLL. You can run them also on 64 bit edition of OS (for example Windows 2003 server 64 bit edition, Win 2008 64 bit) and IIS ver 6.0, 7.0, 7.5 and later.

There are two simple ways to run the 32 bit DLLs under 64bit OS.

Switch IIS to 32 bit mode
Create a COM+ application with ScriptUtils.ASPForm

Switch IIS to 32 bit mode

IIS 6.0, Windows 2003 64 bit edition

See Running 32-bit Applications on 64-bit Windows (IIS 6.0).

Windows Server 2003, Service Pack 1 enables IIS 6.0 to run 32-bit Web applications on 64-bit Windows using the Windows-32-on-Windows-64 (WOW64) compatibility layer.
You can setup the 32bit mode using MetaEdit or Metabase explorer and set Enable32BitAppOnWin64 property of W3SVC/AppPools or using adsutil:

cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 "true"

On Windows 2003 64bit (XP) you cannot run worker processes in both 32-bit mode and as well as 64 bit mode, all worker processes are in 32 bit mode after this setting. So use 32bit COM+ application for IIS6/W2003 rather.

IIS 7.0, Windows 2008 64 bit edition

Windows Server 2003/IIS7 have the same property enable32BitAppOnWin64, but you can set the property for each app pool. So you can run both 32bit and 64bit application pools simultaneously.
You can create application pool for the upload folder and then set the enable32BitAppOnWin64 property for the pool to true - select "Advanced Settings" of the application pool and set "Enable 32-bit Applications" to true, or run next command:

appcmd apppool set /apppool.name:UploadAppPool /enable32BitAppOnWin64:true

Create a COM+ application with ScriptUtils.ASPForm

Setup COM+ Application

1. Create a new COM+ application

Go to Administrative tools - component services (or Start, Run, type DCOMcnfg)
Go to Component services -> Computers -> My computer -> COM+ applications
Right click COM+ applications, new application
Create an empty application named AspForm
Enter a name of the new application (for example, "AspForm")

Create a new COM+ application - Application for upload component

Create a new COM+ application - name the application

2. Add ScriptUtils.ASPForm component

Expand ASPForm application
Right click Components, Click New, Component
Click Import component(s) that are already registered
Select ScriptUtils.ASPForm component

Add a new component to COM+ app - the upload component

Add a new component to COM+ app - select the upload component

3. Set permissions and config the COM+ application

Right click AspForm application, click properties
In the Advanced tab, set "Leave running when idle"
Set identity and security for the main process of AspForm application

For example, if you want to call the application from an ASP page, can do either:

* Disable access check for the AspForm application Simplest way

Right click for COM+ app properties
On security tab uncheck "enforce access checks for this application"

* or For the anonymous IIS user

Open Component Services
Right-click My Computer, and then click Properties.
On the COM Security tab
Click "Edit Limits" in the "Launch and Activation Permissions" area
Add the anonymous IIS user.
Must either be
1) a built-in account like administrator or guest. Or
2) must be a domain user
Give them full permissions

* or can (if on a domain):

Add the anonymous IIS user to the "Distributed COM Users' built-in domain group. The anonymous IIS user must be a domain account.

Set permissions for COM application - Create a new COM+ application

Now you can call the 32bit component ScriptUtils.ASPForm from any 32bit or 64bit IIS application.

    Set ASPForm = Server.CreateObject("ScriptUtils.ASPForm")
