You're right, it worked! Thanks for your help. EDIT: But there is a small problem - well, it's more an aesthetic thing - layers with "Visible" unchecked come out completely empty (transparent, in PNG)! I guess this is unavoidable, but I wonder if there is a way to force it to save normally? Otherwise, I'll just make all the layers visible.

I've been using Paint.NET since before 3.05, so maybe there's some garbage left behind in the registry? I'll give it a try. EDIT: No, it's still giving the same error. And I haven't found anything suspicious in the registry, either.

No luck. After reinstalling, "PdnLib.dll" is still missing.

I've been looking for something exactly like this recently, almost tried to write one myself... But when I open it, it won't run, I just get this error message: System.IO.FileNotFoundException: Could not load file or assembly 'file:///C:\Program Files\Paint.NET\PdnLib.dll' or one of its dependencies. The system cannot find the file specified. File name: 'file:///C:\Program Files\Paint.NET\PdnLib.dll' at System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, Boolean forIntrospection) at System.Reflection.Assembly.InternalLoadFrom(String assemblyFile, Evidence securityEvidence, Byte[] hashValue, AssemblyHashAlgorithm hashAlgorithm, Boolean forIntrospection, StackCrawlMark& stackMark) at System.Reflection.Assembly.LoadFrom(String assemblyFile) at ILikePi.FileTypes.LayerSaver.Program.b__0(Object sender, ResolveEventArgs args) I have Paint.NET 3.36 installed, and I checked the program's folder, but the file doesn't exist (of course). Where can I find it, since it apparently didn't install with Paint.NET?
