Invalid archive: open/read error!

I'd tried to extract NSIS executable file (you said all 7-zip formats are supported) with SevenZipShap and catched this

"SevenZip.SevenZipArchiveException was unhandled  Message="Invalid archive: open/read error! Is it encrypted and a wrong password was provided?\nIf your archive is an exotic one, it is possible that SevenZipSharp has no signature for its format and thus decided it is TAR by mistake."

7-zip can extract this file!

File info:

Scanning -> E:\InputData\ExecFiles\Package\NSIS\ccsetup230_NSIS.exe

File Type : 32-Bit Exe (Subsystem : Win GUI / 2),

[-= Installer =-] Nullsoft SFX Setup v2.46- Scan Took : 0.953 Second(s)


My code:

using (SevenZipExtractor extr = new SevenZipExtractor(@"E:\InputData\ExecFiles\Package\NSIS\ccsetup230_NSIS.exe"))





What is wrong? Can i extract this file with SevenZipShap ?
