Hi,
I built a CustomAction.dll via the following command and then built it into the installer. cl.exe /LD /I PATH_TO_WIX_SDK_INC customAction.cpp /link AdvAPI32.Lib Version.Lib User32.Lib Msi.Lib wcautil_2008.lib dutil_2008.lib while, when running the installer, the error dialog poped up and I found the following from log: "Error 1723 . There's a problem with this windows installer package. A DLL required for this install to complete could not be run. Action MY_ACTION_1, library: C:\Windows\Installer\MSI893B.tmp" In my customAction.cpp, I've added '__declspec(dllexport)' to related methods incl. MY_ACTION_1. Do you have any idea what's wrong here? Thanks! -ofox ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
