RegDLL + could not load DLL

Hi...I need some help with RegDLL. Everything I do it just keeps telling me: "could not load DLL". Here is the script:

Section "Register DLL files" SEC01

SetOutPath $INSTDIR\Components
RegDLL $INSTDIR\Components\Some.dll

SectionEnd

How should I proceed?😱

Same thing happens for:

Exec "regsvr32.exe $INSTDIR\Components\${DLLname1}"

There are probably some missing dependencies. Use Dependency Walker for a complete list of dependencies.
