Thank you for your answer.
I would be glad if you could solve this problem in a future release.
Providing a special variable containing two backslashes would work for me but I think this is still not the best solution because one could still not write, for example, 3 or more backslashes to an ini file. (I know this is hypothetic, but hey, a good installer should not restrict the user

)
So I think it would perhaps be better to make one backslash out of two. This would keep the current logic, but also enable the customer to write 2 backslashes by typing in 4 (...and 3 by typing 6 and so on).
Please let me know if you plan to solve this problem as I don´t know how I coud use the 'Write to TextFile' command to edit a line in the middle of an ini file.
Greetings,
Mike
