Contents

Getting QCAD

There are two ways how you can get the QCAD software:

• From a DVD you purchase from the QCAD website.
• As a file you download over the Internet after ordering your license online.

In either case, you will receive the same files that are required to install QCAD on the hard disk of your computer. Both the download site as well as the DVD contain multiple files for different operating systems. The following sections will explain which file to use for your operating system and how to install it.

Installing QCAD under Windows

This section is only for users of the Windows operating system.

Getting the Setup File

Finding out if your Windows is 32bit or 64bit

If you are not sure if you are running a 32bit or a 64bit version of Windows, please refer to the Windows web site to learn how to find out.

In case you have a DVD, insert it now into the DVD drive of your computer.

1. A DVD icon appears on your desktop. Double click on it to show the contents of the DVD.
2. If your version number of macOS starts with 10.14, you will need to install the file named installation/macOS/qcad-3.x.x-pro-macos-10.14.dmg. In this case you are using macOS 10.14.
3. If your version number of macOS starts with 10.10, 10.11, 10.12 or 10.13, you will need to install the file named installation/macOS/qcad-3.x.x-pro-macos-10.10-10.13.dmg.
4. If your macOS version number is lower, use the appropriate installer which covers that version.
5. Note that ‘3.x.x’ in the file names stands for the version of QCAD you have purchased, for example ‘3.22.1’.

Installation from Download

If you have purchased the downloadable version of QCAD, use your browser to access your personal download area. You can find detailed instructions in the e-mail you have received after your purchase. Most likely, you can simply click on a link in your e-mail application or web mail to go directly to the QCAD website and access your download area. In the download area, download the file that is labeled with the version of your macOS installation, for example «macOS 10.14», «macoS 10.10-10.13», etc., depending on your version of macOS. After the download has finished, use Finder to locate the file on your hard disk.

Installation

Double-click the file you have located in the previous section either from the DVD or from the folder to which you have download it. The file is a disk image that contains the QCAD application. By double-clicking on it, the contents of the file is shown. Drag the QCAD Application icon to the Applications folder that is shown in the same Finder window for convenience.

Launching QCAD

QCAD is now installed on your system. To launch it, open the Applications folder and double-click on the application icon QCAD.

Uninstalling

To remove QCAD from a computer, simply drag the QCAD icon from your Applications folder to the Trash icon in your dock.

Installing QCAD under Linux Systems

This section of this page is only for users of the Linux operating system.

For the sake of brevity, the version numbers in these instructions are indicated as 3.x.x. Replace this number with the actual version number of the downloaded / purchased QCAD release, for example 3.22.1.

Getting the Correct Installation File

The installation file for Linux Systems is called qcad-3.x.x-pro-linux-x86_32.run or qcad-3.x.x-pro-linux-x86_64.run, depending on the architecture of your Linux system (32bit or 64bit).

Alternatively, there are also tar.gz archives for advanced users who wish to install QCAD manually.

Installation using the installer (.run)

The recommended way to install QCAD on a Linux system is on the console. Please open a console application such as Konsole or xterm. If you have a DVD, insert it into your DVD drive and copy the correct file to your hard disk. For example:

Replace ‘myname’ with your login name. The exact location where your DVD drive is mounted might be different and depends on your Linux distribution.

Navigate to the location where you have copied or downloaded the installation file. You can use the command cd for that:

Now install the file by making it executable and run it:

This will create the directory /home/myname/opt/qcad-3.x.x-pro-linux-x86_32 which contains the QCAD application.

Installation using the tar.gz archive

Extract the tar.gz file into any directory of your choice. For this example installation, we use /home/myname/opt:

Launching QCAD

Change to the directory /home/myname/opt/qcad-3.x.x-prof.linux.x86_32 where you have installed QCAD and launch QCAD from there:

Troubleshooting

If QCAD does not run, you might not have all dependencies (required system libraries) installed.

You can check for unmet dependencies as follows:

If you get any «Not found» messages, you need to install the appropriate packages / libraries first.

If you get errors related to GLIBC, you’ll have to install the Qt 4 legacy package (with «qt4» in the file name).

32bit QCAD on 64bit Linux

It is also possible (though usually not recommended) to install 32bit QCAD on a 64bit Linux distribution. Most 64bit Linux distributions require additional libraries to be installed before 32bit QCAD can be run:

Fedora 17, 64bit

Some 32bit libraries need to be installed. Since 64bit library versions have to match with 32bit library versions, some 64bit libraries might need to be updated first (alternatively, you can also install older versions for the 32bit libraries).

OpenSUSE 12.1, 64bit

Install the following packages with the YaST — Software Management tool, including automatically resolved dependencies:

OpenSUSE 12.2, 64bit
OpenSUSE 12.3, 64bit

Install the following packages with the YaST — Software Management tool, including automatically resolved dependencies:

Ubuntu 12.04, 64bit
Ubuntu 12.10, 64bit
Debian 6, 64bit

Install package ia32-libs, for example using apt-get:

Some distributions (e.g. Debian 6, 64bit) also require a package called ia32-libs-gtk:

Uninstalling

When using the QCAD installer, QCAD installs into

/opt, that’s the opt directory in your home folder, for example /home/user/opt if your user name is «user». To uninstall QCAD, simply remove the QCAD installation directory, for example
