If it were possible to award no asterisk I would do it in this case. The software will run on Windows XP Service Pack 3, according imprint. That's right, definitely not, because the dynamic library is "ericapi.dll" not loaded. So anyone who relies on it, that the program under Windows XP SP3 is fully operational, will be disappointed. The tax return can not be bothered with Elster in the case. I had to carry on a different computer with a newer operating system reinstall. Who has not the possibility of the need to print everything and send it to the tax office. And I can not see any advantage over the forms created by the tax office.
