I have a dll implementing a couple of custom actions that are used in a 64-bit msi installer.
When the dll is built as 32-bit dll, the custom action loads and runs just fine. When the same dll is built as 64-bit, the installer tells me "InstallShield DLL Custom Action: Failed to extract file 'mycustomaction.dll' from the binary table."
The installer includes components that are marked as 64-bit, and the Template Summary is set to "x64;1033".
Any ideas how I can get a 64-bit DLL to work as a custom action?
