When trying to run regasm in Win2008 Server:

regasm "C:\Program Files\FooProg\Bar.dll" /tlb:"C:\Program Files\FooProg\Bar.tlb"

I get the following error:

RegAsm : error RA0000 : An error occurred while saving the exported type library: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

what does this mean

That error mostlikely comes up because you can't delete a corresponding .tlb file. Two other suggestions:

  1. Stop IIS and attempt to register again:
  2. Stop IIS, remove .tlb files from wherever your DLL file is and then attempt to register again.
  3. Close all IE/IIS/DEV tools (they might be keeping some files in read-only state) and then attempt to register your DLL
