Installation and Upgrade¶
Before installing Alyvix, first check that your setup meets the system requirements. If it does, you will then need to install Python on your Windows machine before installing Alyvix itself.
Alyvix assumes that you have one virtual or physical machine exclusively dedicated to running Alyvix test cases.
You should check that your designated machine meets the following requirements before you install Alyvix:
Screen color depth: 24-bit RGB or 32-bit RGBA
OS: Windows 64-bit 10, Server 2012, 2016 or 2019 (32-bit versions of Windows are not compatible with Alyvix)
Hardware: 2 CPUs and 4GB RAM
Follow this procedure to install Python on your system:
64-bit Windows installer for Python version 3.7.6. Alyvix is not compatible with 32-bit versions of Python.
Start the installation by right-clicking on the executable and selecting “Run as administrator”. Check the box “Add Python 3.7 to PATH” and then choose “Customize installation”.
On the second panel all the option boxes should already be checked. Click “Next” to continue.
On the third panel, make sure the advanced options are set as shown below. Then under “Customize install location”, insert the recommended location
C:\Python37\. Finally, click on “Install”. At this point Python will begin installing, typically requiring about 5 minutes.
The installation is correct if the following command returns a version number rather than an error message (if not, you will need to edit your
C:\> python --version Python 3.7.6
Alyvix itself is installed via
pip, the official Python package manager.
automatically detect that your system is running Python 3 and will install Alyvix 3,
placing all executables in the directory
The Alyvix installer is launched from the command prompt that, like the Python installer, must be started in Adminstrator mode. Only this single step is required:
Run the following command to download and install the latest Alyvix master release along with all of its dependencies:
C:\> pip install alyvix
We recommend you place your Alyvix test cases in a separate data directory.
Only two steps are needed to upgrade to the latest version:
Save all of your currently open projects
Close all Alyvix user interfaces and applications
Terminate all running Alyvix processes
Upgrade Alyvix with pip
Start a Command Prompt in administrator mode
Run the following command to download and upgrade to the latest Alyvix master release along with all of its dependencies:
C:\> pip install --upgrade alyvix
In order to create an offline installation, you will need two machines:
An internet-connected installer machine with a working Python 3 installation to serve as a source for downloading the required software packages
A second target machine that will serve as the offline probe
Both machines must meet the second system requirement above, and have access to removable media in order to physically transfer the software from the installer to the target.
The following steps will then enable you to install Alyvix on the target machine:
On the installer Windows 64-bit machine with an existing Python 3 installation (not Python 2):
Create a new directory with appropriate permissions
64-bit Windows installer for Python version 3.7.6to that directory
Download the Alyvix application and its dependencies with this command:
C:\...\MyFolder> pip download alyvix
Copy the entire directory onto the removable media, then copy that directory onto the target machine
Use the Python installer now on the target machine to install Python following the instructions above
Open a command prompt in the directory on the target machine and install Alyvix with this command:
C:\...\MyFolder> pip install alyvix-3.1.5-cp37-cp37m-win_amd64.whl --no-index --find-links .
Check that the installation was successful by starting Alyvix Editor:
If the Editor window appears, the installation was successful.
Uninstalling Alyvix and Python¶
To uninstall Alyvix, regardless of whether you also want to uninstall Python, run the following command in a Command Prompt or Power Shell with Administrator privileges:
C:\> pip uninstall alyvix
Pip will list the packages to be removed, and then ask for confirmation.
If you only use Python to run Alyvix, you can now also remove Python itself. Go to
Start Menu > Windows Settings > Apps, scroll down, and remove both
Python 3.7.6 (64-bit) and
Python Launcher. The process may take up to 5 minutes.
Once completed, you can also manually remove the
C:\Python37\ directory (or whichever
directory you specified during installation) and either archive or delete your test case
The Python installer does not remove environment variables, so if desired you can manually remove them at System Properties > Environment Variables > System Variables > Path.
Below are some potential installation problems and their solutions.
“Python” command does nothing or launches Microsoft Store on Windows 10
This error occurs when during installation steps #2 and #4 you did not check the boxes to add Python to the path and environment variables. Typing the python command in the command prompt under this condition will launch Microsoft Store in an attempt to install it from there.
To correct this situation you will need to either (1) uninstall and then reinstall Python, or (2) manually add the appropriate paths in the System Properties > Environment Variables panel.
“ImportError: DLL load failed” — Failure to Import Tesseract OCR
This error is caused by a missing dependency of the Tesseract OCR module, which requires that the
vcomp140.dll be present in Windows during installation by
File "C:\Python37\lib\site-packages\alyvix\core\tesserocr\__init__.py", line 1, in <module> from ._tesserocr import * ImportError: DLL load failed: The specified module could not be found.
You can fix this problem by installing the Microsoft Visual C++ Redistributable for Visual Studio, which contains the required file. It’s available at https://aka.ms/vs/16/release/vc_redist.x64.exe .
