FAQ (Frequently Asked Questions)

|Can I use E&T as portable app on a USB memory stick?||
Yes, E&T can be installed and used as portable app on a memory stick. This allows the use of the program on multiple computers without (as previously required) copying the file Userdata.mdb. You do not even have to install it on the other computers! There is only one exception: the database components ("MDAC") by Microsoft must be present on the computer on which you want to run E&T. They are usually installed by default on newer computers (Windows 2000 and above). If necessary, you can install MDAC on older computers at any time. Please check the information at Downloads / database components on this website..
To use E&T as portable app, please follow our guidelines for "Installation and use on a memory stick"
|The stars appear as eggs/ovals on my notebook display||
This problem occurs with displays that have non-quadratic pixels. Solution: Edit an entry in ET.INI to stretch the stars in the vertical axis. You need to change the key called "AspectRatio" in the section "[Miscellaneous]". Simply insert the factor by which the stars must be stretched vertically to be displayed as circles. On a 16:9-display this is approximately 1.1
The entry in ET.ini should look like this

|How does the licensing work?||
There are four steps for licensing:
|What do I have to pay special attention to?||
Please fill out the information (serial number, user name and license number) carefully! The safest way is to insert user name and license number via copy&paste (Ctrl-c/Ctrl-v). Please note that the following characters can easily be mismatched:
|What happens if the serial number is wrong?||
If you enter a wrong serial number into E&T, you will get an error message and the program will start as demo version. You'll be asked for the correct serial number at every program-start - so you have an indefinite number of tries, if you accidentally enter the wrong serial number.
|What happens if I use the wrong user name?||
The user name under which you operate the program and the user name that you specify in licensing must be identical. We strongly recommend you use your first and last name.
|Why can the licensing fail?||
The online-licensing checks your serial number. If it has already been used, you won't get a licensing number. If you enter a wrong serial number, you'll receive an error message. If you enter the wrong user name, the license number will not work on your system, because you provided a different user name there.
|What happens if I lose my license number?||
Please note down serial number and license key carefully. If you can't find your license key, send an email to firstname.lastname@example.org. Please mention your full name, software version, and serial number. We will answer as quickly as possible.
