Hello i have a known problem:
I add a new path to the environment variable PATH. After that i start a program who needs this PATH variable, but gets still the old one.
I found many posts where the people use:

| CODE |
sParam = "Environment"; pParam = &sParam; pResult = &lResult; if (SendMessage(HWND_BROADCAST, WM_SETTINGCHANGE, 0, pParam) = 0) then |
The SendMessage-Command returns SUCCESS, but i get no update. I tried now many hours in many ways, with SetRegValue, with batch-files and with setx.exe. (With and without delays)
For many people the SendMessage method works, so i must do something wrong.
OS: Windows XP SP3
Can anybody help me, please????

If I recall correctly the MSI engine doesn't process that broadcast message.
Did you try ChangeDir ?

Try using SetEnvironmentVariable to change the variable for the current process.
Can you provide more information on what you're trying to do?

I solved it for me with a batch file.
Within the setup i have to start an application (exe file) wich needs an entry in the PATH Enviroment-Variable. Its the path to the SQLBase server.
My working solution is following:
I wrote a batch file with input parameters. I read the enviroment variable with InstallScript and than i set it in the batch file. After that i start in the batch file the exe file, wich has now for this session the new enviroment variable. I also set it in the registry to have the variable after the setup available, too.
Sorry for my bad english.
