Issue Description
If your Archicad license expires after March 23, 2027, you may be unable to start the program or you might be asked to renew your license, even if your serial code is valid. This affects mainly School Licenses.
Solution
Update to Archicad 27.3.4 or Archicad 28.2.0. where the issue has already been resolved. Archicad 26 and earlier will not work wit Serial Codes that expire after March 23, 2027.
