Hello,

I don't understand the language of images, but it seems that the message is that Allplan 2025 cannot open files from a version higher than 2025.
Could Allplan 2026 have been installed on Allplan 2025 data?
If so, uninstall Allplan 2025 and use only Allplan 2026.

Süleyman Bey,

Lisanslama sisteminde değişiklik olmuş sanırım, lisansları şimdi başlat ikonuna tıklayarak yeni sisteme taşıyabilirsiniz. Problem çözülmez ise programı satın aldığınız yere başvurmanız gerekebilir.
