how do you do it if the key is turned off
dear yoga
key must be correct encryption and decryption. In case you used a function with a key it is mandatory. if you don’t use key then you can learn des64.dll for this case. I checked it and it works fine. i don’t have time to test it about pb7. I think your pb version is too old. you can refer to pb10.5 which is a free key series version. you can use in version 12.6 or higher. You can completely upgrade your projects to versions higher than 2022. But from 2019R3 and above, you must install the runtime when deploying. so you can upgrade to 2019r2 to get new functions. and the compatible optimal faces will be higher. there are many better support functions.
thks!
