Can't remove old programs

[sargan]

I had my OS on C:\ and progams on D:\

The D:\ crashed and has had to be replaced.

Even though I have gone to start>settings > apps .... I cannot install the old programs
I tried IObit Uninstaller and it advises programs removed ... but if I go into start/all apps the folders can still be seen.

How can I remove them .... is there a standard location ins C:\ where I can delete any unused programs that are no longer installed.
Also tried Revo uninstaller - same result

Now normally I wouldn't recommend this program but as you want to remove registry entries for programs that no longer exist so you can reinstall them again, download Ccleaner and run a registry clean. I would confirm all the things it wants to remove as it can suggest things you want to keep.

Have tried that .... it did remove a load of unused DLLs but not these 'part' programs.

see if this advice helps (make backup of registry before you try): http://www.tomshardware.com/answers/id-2457173/failed-secondary-internal-hard-drive-uninstall-programs.html
