No, didn't know about or remember your previous thread, sorry.
I do understand what you mean now though. The copy of XP in C:\WINDOWSXPPRO was
the previous install and C:\Windows is your current, new install. Since you did not
do an install over (Repair Install) the old, the programs that were installed and
available there will not run until you reinstall them under the new copy of XP. You
may get some of them to run buy creating shortcuts to them in Programs or on your
desktop but any associated registry entries will be missing so they may not run correctly.
