In my setup I have a custom action which calls a function from DLL written in C++. In installation this function launches readme file before appearing InstallWelcome dialog. In a body of function there is only a call of ShellExecute and nothing more.
When install my product on Windows NT 4 SP6 with Windows Installer 2.0 after working this function ( as I see in Task Manager this function runs in separate process "msiexec", not in main process msiexec of this installation session ) Doctor Watson is started with access violation for this separate process. It's all OK with installation on NT4 with WinInstaller 1.x and other systems.
May be it is a known problem or no ?
Thanks and sorry for my english.
