I downloaded the wonderful 3cx pbx software free edition and installed in on my laptop, which was running all the modules with no problem at all. But when I tried to install in on my desktop computer, the installation program freezes in the very beginning while "creating user phonesystem__3cx__" appears on the screen. I have four user accounts on Windows XP on this computer and was not able to install the 3cx phone system on the desktop. What I attempted to do was to log in to Windows on safe mode and then install the program. Everything worked fine, but when I run Windows on normal mode, the special account phonesystem__3cx__ is not there, what prevents the PBX central from running properly. Does anyone have a clue about what's happening on my desktop? I was not able to get the software running, not even to install it. Thank you very much in advance.
