vb6 app does not work on win 7

most of them have exactly the same hardware and same build, but yes there are for sure same pc's installation that works and one that does not work and are the same, actually for me is difficult to go and check an all details but I must find a way to install the needed dlls to make it work

unfortunately I cannot do that, I have to provide to the other department that is setting up this PCs with an extra fix, but logically, if the vb6 installation did it I think there should be some way of installing only the dll's and ocx'es, that will have less than 900 mb as vb6 installation is, actually in the meantime I used process monitor to check which dll's and ocx'es the app is using on XP but there are to many to just try to find them and copy them over...
