This distribution of SMath is based on the official Linux version.

Just put the contents of the archive to any directory or storage device.
Launch SMathStudio_Desktop.exe.
Target system must have .net installed.
Not tested under Linux, but using mono could work.

In order to use the Maxima plugin, you need to install the Maxima system on your computer.

The following modifications have been made:

1. 32bit tagged executable SMathStudio_Desktop.exe as provided by Viacheslav Mezentsev.
Source: http://en.smath.info/forum/yaf_postst755_Mathcad-EFI-plugin.aspx
Reason: compatibility with Mathcad EFI and 32bit legacy libraries (mathlib, steamtables)

2. Added file "portable.version" to root directory of installation. 
This ensures that the settings and extensions are saved here and not in the users appdata/roaming system 
directory. This ensures the installation to be really portable.

3. Available plgins already downloaded to extensions directory
Exceptions: XLSX import/export and Maple Wrapper, Matlab C++ Math Lib (to keep the file size small). 
These plugins have to be downloaded by the user in case needed.

4. mathlib and steamtables installed to userefi directory of Mathcad EFI plugin.

5. Added the matrix editor by P. Streipardt
http://smath.info/wiki/Tools.ashx

6. Added preliminary integrated bilingual (german/english) help system.
Access is via Button "Reference book" on the tool bar or in the help menu.
The material has been installed in the folder "book" in the installation root. 
The original file "Contents.sm" is modified, the other help pages are in the subdirectory "activebook"
They may be opened as ordinary SMath Sheets and are interlinked with the other pages.
home file is "Handbook.sm". 

7. Small changes to entries/units.xml (added % and some other units)

The help pages are full of typos, errors, omissions, missing translations etc. Feel free to correct the files and send 
them back to me:
