Error compiling: *.xml.p7m files not found

[nooborka]

Hi! I'd really need this extractor but I can't compile it because I get 75 errors of the following kind:
Severity Code Description Project File Line
Error Could not copy the file "...\P7MExtractor-master\ConsoleApplication1\p7m\IT05754381001_01EQX.xml.p7m" because it was not found. ConsoleApplication1

Is there a solution?

Solved: I had to remove those files from the project. New issue: I get File-Valid: false but the file is almost certainly valid
