Question

Any pointers for troubleshooting 2737 Could not access custom action [2], entry [3], library [4] Available in Windows Installer versions 1.0, 1.1, and 1.2.?

Answer

First, start with the Windows Installer Error Messages reference as you have done.

Second, one needs to recognize this error points to a problem with the custom action DLL.

Third, track backwards. Export the binary from the Binary table.

Forth, try running depends.exe or something on the DLL

This should get you started.
