Upgrading from 14.0- to 14.1+
Starting with version 14.1, the Wolfram application was introduced as the new way for users to access Mathematica, Wolfram|Alpha Notebook Edition, Wolfram|One, and Finance Platform. With this update came a number of changes that are not backward compatible. Visit the links below to learn more:
Upgrading from Mathematica to Wolfram
Mathematica, Wolfram|One, and other products are now accessed via the new unified WOLFRAM app
My recommendation: use the “Freshly Install …” alternatives described in the first link above.
Symbolic Computations — fall semester course
In the upcoming academic year 2024/25 the fall semester course Symbolic Computations will take place again. Therefore, I would like to take this opportunity to offer those of you who use the Wolfram Language in Mathematica extensively for science, teaching, or simply daily work, and who would like to become more familiar with the principles of programming in this language, the opportunity to attend this course without obligation. Of course, it is also possible to attend only the lectures (or parts of lectures/exercises) of your choice.
Classes will be held on Tuesdays from 15:35 to 18:50, with one or two breaks, in the seminar room of the Institute of Physics (room number 316), starting on October 1st. The capacity of the room is sufficient for approximately 4 additional participants.
Currently I am the Wolfram Site Programs Administrator for the Institute of Physics at the Silesian University in Opava.
A distinction should be made between the following two licences:
Employee license L5040-3869 Mathematica Comprehensive Site (Network Mathematica for Sites and total of 26 Mathematica Site Home Use licenses as a Premier Service Benefit): intended typically for desktops permanently located in reach of the Network License Manager of the Silesian University (activation through a Wolfram Network License Server whose domain name will be provided to eligible users upon request), and for laptops of scientific and educational staff independent of the availability of the network license server (activation through an assigned Activation Key).
Student license L5040-3865 Mathematica Student Comprehensive Site (total of 25 licenses): intended for students’ personal laptops independent of the availability of the network license server (activation through an assigned Activation Key). Each eligible student will be provided with a legal school license of the Wolfram Mathematica program for the duration of the course, at least until the relevant exam has been successfully passed (allocation and installation will be handled after registration before the first lecture).
From a functional point of view, both are equivalent, but differ in licensing terms. Anyone interested in installing the program please notify me at one of the contact in the page header. The current license will expire at the end of the 2026, but we hope on having funds for extending it for years to come.

For Version 14.1 and higher of Wolfram-based products, such as Mathematica, visit the Installing Wolfram tutorial.
For lower versions, see Installing Mathematica tutorial for details.
Once the installation of your Wolfram product (such as Mathematica) is complete, upon first launching it you will be presented with the Wolfram Product Activation dialog. The Activating Mathematica tutorial shows you how to do this.
Paclets are units of Wolfram functionality, packaged up in a way that allows them to be discovered, installed, updated and integrated seamlessly into the Wolfram environment. They work “behind the scene”, an ordinary user is unaware of their presence and does not even have to care. The Wolfram developers usually deliver many types of content, including Wolfram Language files, LibraryLink libraries, front end resources like palettes and stylesheets, Java libraries for use with J/Link, documentation notebooks, etc. in the form of paclets. Simply copy-paste the following code to a notebook and evaluate it on your computer. Before upgrading to Wolfram version 14.1, my paclet repository was about 5 GB (understandably, it is now much smaller after a fresh install of version 14.1):
Module[{p, n, s, d = $UserBasePacletsDirectory},
p = FileBaseName /@ FileNames[All, FileNameJoin[{d, "Repository"}]];
n = p // Length;
s = UnitConvert[Total[Flatten[Values[
Apply[List, FileSystemMap[FileSize, FileNameJoin[{d, "Repository"}], Infinity], Infinity]
] /. {n_Real, v_String} :> Quantity[n, v]]], "Gigabytes"];
Print["A total of ", s, " in ", n, " paclets:"]; p
]
You can learn more about paclets by following these links.
Basic user operations with paclets
Paclets are usually sourced from a remotely located site called a Paclet Server (although a local site is also possible). By default, the Wolfram Research Paclet Server and the Wolfram Language Paclet Repository are known to your system (input and output are on light gray and pink background, respectively):
With[{p = PacletSiteUpdate[PacletSites[]][[All, 1]]},
TableForm[Values@p, TableHeadings -> {None, First[Keys@p]}]
]
| URL | Name | Local | Type |
| https://pacletserver.wolfram.com | Wolfram Research Paclet Server | False | Server |
| https://resources.wolframcloud.com/PacletRepository/pacletsite | Wolfram Paclet Repository | False | Server |
None of the above sites should be removed (removal instructions are below). However, you can add other paclet sites (including mine or your own). Adding a remote paclet site from the list below is done by substituting the appropriate URL and a name of your choice into the PacletSiteRegister function. For example:
PacletSiteRegister["https://is.slu.cz/www/hle0002/paclets", "Some name"]
PacletSiteObject[<|URL -> https://is.slu.cz/www/hle0002/paclets, Name -> Some name, Local -> False, Type -> Server|>]
The Paclet Server at https://is.slu.cz/www/hle0002/paclets/ is now known to your system:
With[{p = PacletSites[][[All, 1]]},
TableForm[Values@p, TableHeadings -> {None, First[Keys@p]}]
]
| URL | Name | Local | Type |
| https://pacletserver.wolfram.com | Wolfram Research Paclet Server | False | Server |
| https://resources.wolframcloud.com/PacletRepository/pacletsite | Wolfram Paclet Repository | False | Server |
| https://is.slu.cz/www/hle0002/paclets | Some name | False | Server |
Now you can install, for example, the Snapdragon paclet:
PacletInstall["Snapdragon"]
If you no longer need the Snapdragon paclet, you can uninstall it:
PacletUninstall["Snapdragon"]
If you no longer intend to use the Paclet Server “Some name”, you can unregister it with PacletSiteUnregister; it will no longer be known to the system:
PacletSiteUnregister["Some name"];
With[{p = PacletSites[][[All, 1]]},
TableForm[Values@p, TableHeadings -> {None, First[Keys@p]}]
]
| URL | Name | Local | Type |
| https://pacletserver.wolfram.com | Wolfram Research Paclet Server | False | Server |
| https://resources.wolframcloud.com/PacletRepository/pacletsite | Wolfram Paclet Repository | False | Server |
Read the Working with Paclets guide to learn more commands, options and capabilities of the paclet system from both a user and developer perspective.
Paclet Servers at the Institute of Physics
Within the framework of the Information System of the Institute of Physics, I operate, maintain and contribute these own paclet servers:
I am working on a new Paclet Server at https://is.slu.cz/www/hle0002/wolfram/pacletarium/ that will replace the paclet server listed below.
My Paclet Server at https://is.slu.cz/www/hle0002/paclets/. Warning: This paclet server is outdated and will be replaced by a new one (see above). However, I still use my own paclets Snapdragon and Cuticurve, although their use is deprecated (unfinished documentation, needs code polishing). Until they are replaced by their successors, this page will be kept alive.
Paclety – jak na ně? (Paclets – How to handle them?) Presentation and Paclet Server at https://is.slu.cz/www/hle0002/wolfram/sum21/ for online meetings of Mathematica users, 2021-02-09 (available in Czech only).
