How to Fix Administrative Deployment for 64-bit .NET Framework Redistributables
While investigating patching scenarios for 64-bit SKUs I found that for source extraction and administrative installs the 32- and 64-bit files map to the same paths. This, unfortunately, shipped in beta 2. The problem this causes is that a 64-bit call to
LoadLibrary will fail to load a 32-bit DLL such as mscoree.dll. Only the 64-bit libraries wow64.dll, wow64win.dll, wow64cpu.dll, and ntdll.dll can be loaded into a 32-bit process, so the error dialog above or a similar error is displayed. You might also find the following log lines in your log file:

The problem is that when extracting source files as we do for our patch build system, or creating an administrative installation no custom actions are run. Many custom actions are used to set directory paths for components that are provided by merge modules (MSMs), which is the majority of files. Since the 32-bit files must be installed to support 32-bit applications, the x86 mondo MSM is consumed which uses the same source and destination directory names.
To enable administrative deployment for beta 2, you must either modify the MSI or create a transform, which I recommend. This gives you flexibility without changing the target MSI.
There are several ways of creating transforms, from programming against the Windows Installer APIs or using the object model to using Orca from the Windows Installer SDK, part of the Platform SDK. To install Orca – a graphical tool for editing MSIs, MSPs, or MSMs; and creating transforms – you must install Orca.msi in the Bin sub-directory of your Platform SDK installation root.
To create the transform, follow the steps below. You can also simply skip the steps and download and extract pathfix.mst.
- Download either or both of the 64-bit redistributables you want to deploy:
- Extract netfx.msi from NetFx64.exe:
NetFx64.exe /c /t:”<path>”
- Right-click on netfx.msi and select “Edit with Orca”. If you do not see the context menu item, you can open Orca from your Start -> Programs menu and click File -> Open and select netfx.msi.
- On the Orca menu, click Transform -> New Transform.
- Select the “Directory” table and click the “Directory” column to sort by the directory ID.
- To change the source and destination directory names:
- Find “DD_Framework_X86.3643236F_FC70_11D3_A536_0090278A1BB8” in the “Directory” column and change its value to “frmwrk32|Framework_x86” (without quotes).
- Find “DD_ProgramFilesFolder_X86.3643236F_FC70_11D3_A536_0090278A1BB8” in the “Directory” column and change its value to “PFiles32|Program Files_x86” (without quotes).
- Find “DD_SystemFolder_X86.3643236F_FC70_11D3_A536_0090278A1BB8” in the “Directory” column and change its value to “Sys32|System_x86” (without quotes).
- Find “Framework.3643236F_FC70_11D3_A536_0090278A1BB8” in the “Directory” column and change its value to “frmwrk|Framework” (without quotes). This step is optional.
- Optionally, you can set to what product(s) your transform applies by clicking the Transform -> Transform Properties menu. I recommend checking “Same Language”, “Same Product Code”, “Product Version is Equal”, and “Major, Minor, and Update Versions” to only target beta 2 since changes were made since beta 1 and this bug has been fixed in time for RTM.
- Save the transform to disk by clicking the Transform -> Generate Transform menu item in Orca. For the examples below I called the transform file pathfix.mst.
When creating an administrative installation now, pass
TRANSFORMS="<path>pathfix.mst" to the command line and copy the transform to the target directory like in the following example:
msiexec /a netfx.msi /l*v netfx_admin.log TARGETDIR=\SERVERSHARE TRANSFORMS=pathfix.mst copy pathfix.mst \SERVERSHARE
To deploy the application, you must also specify the transform when installing like in the following example:
msiexec /i \SERVERSHAREnetfx.msi TRANSFORMS=\SERVERSHAREpathfix.mst
This bug has been fixed in later builds of 2.0.
