Changing bitmap #63

Closed cdyer5050 closed 2 years ago

cdyer5050 commented 2 years ago

Adding a custom bitmap and adding the path to the registry or during install with a transform file doesn't work. The login logo never changes. I am using the latest version.

Hello, can you please send us a copy of the registry (HKEY_CLASSES_ROOT\CLSID{FCEFDFAB-B0A1-4C4D-8B2B-4FF4E0A3D978}) and a copy of the logo files you are trying to use ?

Best regards

bitmap&registry.zip Bitmap and registry are attached. I removed the server IP and shared secret for obvious reasons.

Hello, looks like the file format is not supported. Don't know why. I just opened it in Microsoft Paint and saved it as bmp 24 bits and it works. Can you please try it ?

Best regards

Hello, Your BMP was compressed using "Huffman 1D", and Windows need an uncompressed BMP. Source : https://en.wikipedia.org/wiki/BMP_file_format Offset 30 (1E in hexa), the compression byte was 3 (Huffman 1D) in your BMP file, and not 0 (uncompressed) Regards,
