After installing the Pageflip 5.0.3 32bit into a DNN 4.9.5 installation the site reported an error
Required permissions cannot be acquired
This is for a file named MagickNet.  Can you help please?
Could you report exact message in this forum please?
How did this error appear to you? during installation, after put module on a page?
I have a similar error.  I'm running DNN 5.01.02 and 5.0.3 of your PageFlip Module.  After installing with no errors, I go to place your module on a page and get this error:
Aricie.PageFlip is currently unavailable.  DotNetNuke.Services.Exceptions.ModuleLoadException: Could not load file or assembly 'Aricie.DNN, Version=1.23.8.0,Culture=neutral,PublicKeyToken=null' or one of its dependencies.  The system cannot find the file specified.-->
I opened up the bin folder and I see the Aricie.DNN.Modules.PageFlip.dll.  It's properties has the correct 5.0.3 version, so I'm assuming that maybe I'm missing a different dll??
 
Have you installed Aricie.Shared which is free required component for all our modules ? You can download it in download area or on snowcovered.
