Answer:
Thank you for your email request. Please download and install one of the DLUBAL programs using one of the links below. Then delete the author.ini file on your PC, which can be found in the directory C:\ProgramData\Dlubal\Global\General Data\. If the directory is not displayed, please display the hidden files in the options of Windows Explorer. Then, please carry out the activation with this program version. After having finished the activation, the X.07 program versions can also be used.
