Anytime you execute a command that requires a connection to 3DEXPERIENCE, the Connector for Altium Designer opens a login dialog box unless you are already connected. In addition, if you used an earlier version of the Connector for Altium Designer, you might need to migrate data.
When naming files or directories on your local computer, Altium Designer and the Connector for Altium Designer do not support special characters or white space in file and folder names. This requirement applies to the temp directory. You should use d:\temp, for example, instead of d:\temp dir.
