DLGDIAG for windows has stopped working

SOLVED
When installing Western Digital Data LifeGuard Diagnostics - DLGDIAG for Windows
version 1.31 do not install into the default folder C:\Program Files\Western Digital Corporation\Data Lifeguard Diagnostic for Windows.
Program crashes.
Instead install in folder C:\Program Files\Western Digital Corporation then
program works perfectly.
Maybe path name for folder is too long.
Works for V1.31 and V1.24. Hope this helps.
Running Windows XP

Resend previous comment. NOT FIXED.
Work yesterday evening but today it crashes.
If you continue to let the error msg dialog to be displayed
the WD DIAG program will sometimes display after a few seconds.
I give up !!!
