If you want to run your powershell custoamction from support directory using installscript, you can follow below steps
Open your project, Select support files under "Behavior and Logic" and add your script ps1 file.
Now in your project, go to the 'Behavior and Logic->InstallScript' view and under the 'InstallScript->Files' node, right click and add a new 'setup.rul' file (...assuming no file is present already, if so, then skip this).
Once you have the 'setup.rul' file in your project, then there should be a default function added to the script called MyFunction(). You can keep this function name or change it (...remember to update the prototype as well) and you can use the following code...
function MyFunction(hMSI)
// To Do: Declare local variables.
STRING sMySUPPORTDIR, szCmd, szParam, szCmdLine ;
NUMBER nvBufferSize;
begin
// To Do: Write script that will be executed when MyFunction is called.
nvBufferSize = 256;
//Get SupportDir value
MsiGetProperty(hMSI,"SUPPORTDIR", sMySUPPORTDIR, nvBufferSize);
//MessageBox("SUPPORTDIR = " + sMySUPPORTDIR, INFORMATION);
// Setup command line to run ps1 file
szParam=WINSYSDIR64^"WindowsPowerShell\\v1.0\\powershell.exe";
szCmd=sMySUPPORTDIR^"CreateFolderPowershell.ps1";
//szCmd=sMySUPPORTDIR^"test.ps1";
LongPathToQuote(szCmd, TRUE);
szCmdLine=" -file "+szCmd;
//Running Script with Admin Privileges
LAAW_SHELLEXECUTEVERB = "runas";
if (AskYesNo(" Do you like to run our Powershell Script? Which will modify your system settings", YES) = YES) then
Disable(WOW64FSREDIRECTION);
//LAAW_OPTION_HIDDEN is used to hide the powershell window
LaunchAppAndWait(szParam, szCmdLine, LAAW_OPTION_WAIT| LAAW_OPTION_SHOW_HOURGLASS|LAAW_OPTION_HIDDEN);
endif;
end;
// If we want to run script after user confirmation
if (AskYesNo(" Do you like to run our Powershell Script? Which will modify your system settings", YES) = YES) then
Disable(WOW64FSREDIRECTION);
LaunchAppAndWait(szParam, szCmdLine, LAAW_OPTION_WAIT| LAAW_OPTION_SHOW_HOURGLASS);
endif;
