Hmm, did you select the "Remove data files" option?
Nice doesn't touch the Notes data directory
even if the data directory is under the in single user mode by default.
Since you removed your C:\Notes directory you probably deleted your
Notes data directory including the logs.
Can you look in your "My Documents"
folder for a file named "IBMNotesInstallerLog.cab" and send it
to me?
Thanks
