E&T as a portable application on a USB stick
You need a USB flash drive with 4 GB of free space. Choose a model with the highest possible transmission speed.
Create directories on the USB stick with the following names: "ET30" for the installation, "Backup" for backup, "Links" for files that you wish to link to from the object information or from the logbook and "documents" for planning documents.
Afterwards, start the installation program from the DVD. Enter "ET30" on the USB stick as target directory. Select the "Standard" installation, so that also GSC-data and images will be installed. The installation process takes a relatively long time.
If you've already been working with E&T, you can now copy the Userdata.mdb from your installation on another computer into the directory "ET30" on your USB stick.
Now you have to license E&T on the USB flash drive. Start the program by double-clicking the file ET.exe in the directory ET30 and proceed as for installation on a hard drive (serial number, name and license code).
In the program options (start with Tools.Options), set the backup path to the directory "backup" of the USB stick. In the group "default path" of program options, please set the "planning documents" to the previously created directory "Documents". The "File links" should point to the previously created directory "links".
Now quit E&T.
Please locate the file "ET.EXE" in "ET30". Click on it with the right mouse button and choose the command to create a "shortcut". Now right-click on the resulting file "Shortcut to ET.exe" to access the file properties. In the field "Target" you should see "X:\ET30\ET.exe" (X is a placeholder for the current drive letter of the USB stick). Append the following text: " -portable". Do not omit the blank before the hyphen. Click OK.
If you prefer, you can now rename the shortcut as you wish and move it, e.g. to the top directory of your USB stick.
To start E&T as a portable application from the USB stick, use the previously created shortcut. The program asks if it shall run from removable media. If you agree, then all directories specified in the file ET.ini will be changed to match the current drive letter of your USB stick. If you have started E&T accidentally with the parameter "-portable", you can abort here and the paths in the ET.ini (as well as in the database) will remain unchanged.
Please note that E&T will be busy with the backup after the end of the program for a few seconds. During this process, the program logo will be visible, which also appears when you start the program.
Under no circumstances should you remove the USB stick while the program is still writing data to it! Wait until the USB flash drive activity light stops flashing and deactivate the media in the usual manner. If you remove the USB too early, you can damage important files and E&T might fail to start.
If the files "ET_Sys30.mdb" or "Catalog30.mdb" are reported as damaged, you can copy them from the DVD to the directory "ET30" on the stick and thus restore the proper function. A broken Userdata.mdb can be restored from your backup (see below), although you'll lose the last unsaved changes.
Important: Do not forget to backup your Userdata.mdb on an additional medium as soon as possible! If you add new observations or create new plannung documents, we recommend that you copy them and the file Userdata.mdb to your main computer.
Do not trust solely in the functioning and security of your USB stick!
Please consider "E&T portable" as a convenient way to plan your observations or documents on any Windows computer, anywhere. This is a comfortable way to show someone something in mind, but please note that "everything can be lost" if the USB drive does not work properly...
