I read that I have to escape the > and ". But that does not work. The pops up as a command line windows and I can see the output. But the file does not get written.
I already tested without escapes and also without quotation marks. But nothing works. How can get this simple problem solved?
The notation > output is typically processed by the command shell; the way Windows Installer invokes custom actions does not understand this notation. If you need this to work, you will need to invoke the command shell using a command line like cmd.exe /c ..., or equivalent.
