Hi Valerie,
I don't have a .rootrc, other than the one that comes with the ROOT v.
2.23.11 distribution (i.e. the one in the tutorials subdirectory). I
don't know if root is reading this file or not, but I tried moving it
out of the way temporarily (I renamed it to xxx.rootrc), and I got
exactly the same error messages (i.e. the message "dll does not exist or
wrong file extension (.dll)").
Are you able to successfully run ROOT v. 2.23.11 on Win98, or have you
only tested it under WinNT? It would be nice if someone else on the
list could confirm the same behavior I am seeing. I honestly believe
that I have a virgin install of ROOT v. 2.23.11 on my Win98 system - the
laptop is brand new (i.e. so it couldn't have any previous versions of
ROOT laying around, nor any stray .rootrc files, etc.), I downloaded
ftp://root.cern.ch/root/root_v2.23.x86.Windows_NT.tar.gz, unpacked it
with WinZip, set ROOTSYS and PATH as I already mentioned, and typed
"root" at the MSDOS prompt. Given this information, it would seem that
the Win32 build of ROOT v. 2.23.11 may be broken in some way, at least
under Win98.
Any other insights would be appreciated. Thanks for your help Valeri
