Here is a work around for import .edz files to EPLAN 2.2.
Rename the edz file to zip.
Use winrar to unzip it.
In EPLAN,
+ open part management dialog: Utilities -> Parts -> Management
+ open import records diaglog: Extras -> Import
+ Select file type: XML
+ Select file name: look for xml file in subfolder "items\partxml\" in extracted folder
+ Press OK to import.
Hope this help
Checked with EPLAN 2.2 and edz file downloaded from Siemens support site.
