Program Activation

Activation unlocks all features of ProfiCAD. It takes about 30 seconds.

How to activate ProfiCAD

  1. Start ProfiCAD.
  2. In the menu choose Help → Activate (enter key).
  3. Enter the license key you received after your purchase.
  4. Done – the file key.dat is created in the program folder (C:\Program Files\ProfiCAD for ProfiCAD 14 and later, C:\Program Files (x86)\ProfiCAD for version 13 and older). This is your "proof of activation".

⚠️ Keep the license key and the key.dat file in a safe place. It is best to back up the whole program folder.

💡 Pro tip: E-mail the license key to yourself – you will always find it in your mail archive, even if your disk fails.

Activation on a new computer

Your old computer is gone? You have two options:

  • a) From a backup – if you have a backup of the program folder, simply restore it on the new computer. No internet needed.
  • b) With the license key – no backup? Enter your license key again in the same way as the first time.

💡 Pro tip: Option (a) works offline too – ideal for example on a construction site without Wi-Fi.

Activation on a USB flash drive

Want to have ProfiCAD "in your pocket"? Copy the key.dat file from the program folder to the flash drive – into the same folder where ProfiCAD.exe is.

💡 Pro tip: This gives you a fully portable version on the flash drive that you can run on any Windows computer without installation.

Activation on school computers

Do you have a multi-license for a school? Activate ProfiCAD on one computer and then simply copy the key.dat file to the program folder on the other machines. No internet needed.

💡 Pro tip: Copying key.dat is easy to automate with Group Policy or a simple script – it saves you walking from classroom to classroom.
