nced: Despite having ordered and payed for QCAD Professional (thank you!), you appear to be running the free QCAD Community Edition which does not support the DWG format.
Perhaps this edition of QCAD came with your Linux distribution or it might be self-compiled (in the latter case, you would definitely know that).
To use QCAD Professional instead, you'd have to download it form the download link received after purchase and install and run that instead. You also might want to remove the QCAD Community Edition to avoid any confusion.
Accessing your Downloads
An e-mail was sent to you directly after purchase with a link to your download area where you can download the full version of the software and the e-book if applicable. The link is valid until one year after purchase. The e-mail also states until when the link stays valid.
No key or activation of any kind is required. This link can also be used to download the software / e-book again and to download updates until one year after your purchase.
If you cannot find this e-mail, please look also in your Spam or Bulk mail folder.
The e-mail subject is "Order / Commande / Bestellung" + your order number. Please keep in mind that you might have used a different e-mail account when placing your order.
You can request your download link again through our website at:

Do not download the free QCAD packages from our public web site as these are trial versions that cannot be turned into full versions.
