Aamir,
Is your NX_ROOT on your e: drive? what's the exact path ?
Here's a scenario to consider:
1) e:\program files (x86)\CA --> already exists
2) you try to install SDM now, installer detects that you do not have 8.3 enabled
3) you enable it on e: drive,
4) this enforcement somehow does not fix program files (x86) to receive 8.3 yet, because the folder was created prior to enabling 8.3
5) one option in this case is, to stop all programs using e:\program files (x86) folder, rename e:\program files (x86) to e:\ORIG_program files (x86) (NOTE, you cannot append something, you HAVE to Prepend something in this use case). create a new folder called e:\program files (x86) (this folder now should receive the 8.3 name), move the contents of e:\ORIG_program files (x86) to e:\program files (x86)
I'm wondering if you ran into this situation because the options are still showing up as In Progress
