function Func1(hMSI)
STRING PropertyName;
NUMBER nResponse,nvSize;
begin
nvSize=MAX_PATH;
nResponse=MsiGetProperty (hMSI,"TEST",PropertyName,nvSize);
MessageBox("PropertyName:"+PropertyName,INFORMATION);
if (nResponse==0) then
LaunchApp(WINDIR ^ "npp.8.3.3.Installer.x64.exe", "");
MessageBox(WINDIR^ "npp.8.3.3.Installer.x64.exe",INFORMATION);
