Upgrading/Programming a dongle for an ArchiCAD license or Add-ons can be quite a simple task, all one needs to do is insert a key plug and go to the website upgrade.graphisoft.com, select the type of the key plug and start programming.
But there may be issues that would temper with the progress of upgrading the dongle via the above mentioned website, for instance, upgrade not taking place and being advised to install java etc, or may be being prompted to check troubleshooting steps to figure out why the upgrade is not taking place.
But fear not, for the above mentioned problem and/or checking the troubleshooting steps where the website is unable to upgrade the dongle may be avoided. There is an alternative stand alone application called License Activation Tool (LAT), we can use this tool as an alternative to license upgrades. this tool has the same functionality as the upgrade website e.g. Dongle upgrade and license transfers from WIBU to Codemeter. The link to download LAT is: http://www.graphisoft.com/downloads/licensing/ after the download, LAT has to be installed in the computer that is to be used for the upgrading process, and the installation instructions are outlined on the same download site.
It is in very rare cases where we may encounter any problem when upgrading the dongle with LAT. The most common setback is that this tool does not support double-byte/special characters in the Windows login name. A double-byte character set (DBCS) is a character encoding in which all characters are encoded in two bytes. A DBCS supports national languages that contain a large number of unique characters or symbols. Examples of such languages include Japanese and Chinese.
Avoid using language specific double-byte characters in the Windows login name (C:\Users\username path).
