Thanks, it worked after copying winlaunch.alib file to WinUAE folder
I hope you can make this similar problem work also:
If AmiKit X boots using Startup shortcut, and I double-click on a .mp4 or .pdf file inside the Amiga filemanager, that file won't open in a Windows program, like it should when using "Full-window/RabbitHole compatible" configuration in WinUAE.
But if I boot AmiKit X normally, then .mp4/.pdf files inside Amiga filemanager will open just fine in a Windows program.
Is there a similar solution, where another file should be copied to WinUAE folder, like in the previous problem ?
