vb.net - Cannot find the reference specified-Visual Basic 2013 -

i've got new system. trying connect , run system through 64-bit windows 7 pc. company sent me visual basic project that. uses .net framework 4 , windows form applications. target cpu x86.

in references tab, next 3 of com references there "the system cannot find reference specified" statements. when built, project gives namespace errors , warnings because of these objects. other references work fine. i've seen .dll files in debug folder. think generated company before sending me. exist in bin\debug folder.

i've removed 3 references list in project , tried following separately:

1) in project, refer .dll files exist in debug folder. (seems fake way, removes errors when project built. when debug, gives "retrieving com class factory component clsid ... failed due following error: 80040154" error.)

2) copy .dll files in debug folder c:\windows\syswow64 folder, register through regsvr32 "name.dll" in console admin. way, ".dll loaded, dllregisterserver entry point not found" error. (in regedit window, registry editor cannot find id's of references seen in project properties in vb.)

3) item (2), c:\windows\system32 folder instead of syswow64. same error when registering.

4) changed solution platform x86 , tried items 1,2, , 3. still same errors.

do have register these dll files? and, supposed register these dll files exist in debug folder? or supposed generated after build referring 'missing' type libraries in references tab? don't have these type libraries, though.

all suggestions welcome asap. in advance.

you have 3 interop dlls project, correct? these dlls allow use com dll without having talk directly com dlls yourself.

referencing dlls in bin/debug directory should fine, since correct dlls project built with. however, want move them folder before continuing.

what need company sent project original com dlls , dependencies, if any. interop dll called microsoft.phone.interop.dll performing interop microsoft.phone.dll. microsoft.phone.dll needs registered on computer using regsvr32 , need reference interop dll.
