Did you check the "tick" that erases old configs during installation?
Still the same error, when I tried the LNet trunk 2661 with the SR 1.6!!! I do not know why but I see the problem coming from the SSL units of the WebLaz.Any one tried to install WebLaz and/or LNet on the SR 1.6?
I have same problem after one year 1.6 was released. How you "install from trunk" ? Where I can find trunk 2661 ? It is so frustrating.. I tried everything, including uninstalling Lazarus and cleaning everything about it.
