Re-installing PSE 10 on Win 7 pro 64

Question

I'm having a issue involving re-installing PSE/PE10 onto my new Win 7 pro 64 home build.
It started with-
I had an issue right in the middle of installing software onto this new machine.
I have multiple Hard Drives installed and during a recovery from being hit with some bugs (malware/virus) during all this installation I thought it best to unplug some of those drives to minimize potential damage.
I had already installed PSE/PE 10 onto those drives and when I finally got back up and running the links to these installed programs no longer worked. Trying to re-define the links proved too much and so I thought a complete re-install of both programs should do it.
I un-installed both programs
Un-install, cleaned registry, found more folders (reading forums here) deleted those, cleaned registry, rebooted thru several of these processes,..and did manage to re-install PE 10, but PSE 10 is giving me fits and I can't figure out what else to do.
I go to re-install PSE 10 and the only choice I get is to REMOVE the s/w from the pc (even tho it's already uninstalled). Okay, I'll do that and THEN proceed but- after offering to deactivate my software on this pc (okay I can do that) the only option it then gives me is to delete, fine, but when I select that option it then takes me to a window that informs me that the disk doesn't have the room available and even tho other disks are avail to click on, doing so doesn't allow any other selections to be made. The TARGET area (even tho it is for uninstall) is the install disk drive and I can't make another selection. So it ultimately does nothing!
I managed to get PE 10 back onto the drive, what in the world remnants are staying behind to give Win 7 the impression that I still have the program installed and not allowing me to do just that- re-install it??
Could really use some assistance on doing this before I wipe the whole HD as a last resort- ugh!
ps- uninstalled Air, Organizer and any/all folders I could find related to anything Adobe thinking it was interferring with this

Answer 1

I managed to RegEdit those areas but must have gotten heavy heanded in that, after cleaning all instances of Adobe out of the Registry I get another problem. I just went to try and install PSE 10 after doing as much cleaning as I know how;
checking the registry as you suggested
running a registry tool to check for  missing links etc
rebooting after each pass to clean the drive
When I went to install it tells me an error on the windows installer- "The configuration data for this product is corrupt. Contact your suppport"
I must have taken too much out of the Registry. Is there a method to restore? Would that fix the issue?
Thanks for the assistance
ps- FYI, upon trying to run the PE10 installer it seems as if that was going to work. I cancelled out of it until I fix the PSE 10 issue. But it did get further than the PSE installer and no error messages.
