Compile error

[rtgjeg]

I downloaded the latest visual studio and am running the Developer Command Prompt for VS 2022, and I get the following error:

C:\Evil Clippy\EvilClippy-master>csc /reference:OpenMcdf.dll,System.IO.Compression.FileSystem.dll /out:EvilClippy.exe *.cs

Any idea what could be causing this? I'm using a Windows 10 system. Would it be possible to send me a pre-compiled version since it seems to work on your system?

[rtgjeg]
