VB Package And Depl Wizard - dll problem

I have been using VB6 Package and Deployment Wizard several times without any problem.

Now I have got a problem:
Among big number necessary files wizard picked up
MSVCRT.DLL
MFC42.DLL

I Run installation program and got error messages told me:
that MSVCRT.DLL and MFC42.DLL cannot be placed because of access violation.

Could anyone give a hint
1)what kind of code could cause wizard pick up MSVCRT.DLL and MFC42.DLL(usually it was MSVCRT40.DLL and no MFC42.DLL)
2)what could be the reason that installation program cannot write and register dll picked up by the Wizard

Any information will be apreciated
Thank you.

Boris

Have you tried closing everything first?

Thank you, Frank
I did

I know what you mean. If I left open my project during installation, it gives me the whole bunch of similar messages on almost all dlls my project uses.

After closing ALL before instaling only MFC42.DLL and
MSVSRT.DLL remain unaccessible and give error messages.
May be some Windows processes still using them?

Is there general way to avoid this?
