[?]: TIA 12 blocks have password protection

[monirul]

Hi all,

I have project with Siemens TIA portal V12 Sp1 update3 several blocks that we built befor years and they*have password protection.

The problem is that we had lost the password and nobody remembers.

How can I solve this issue and open the block ? may be I can reset the password somehow?

TIA use AES to encrypt code, so decrypt without key is not possible in some degree.
