Hello, the problem is due to the change in the case of the following registry key with IE 7.
HKEY_CLASSES_ROOT\htmlfile\shell\open\command
As a workaround you can change iexplore.exe to be lower case - example:
Change: "C:\Program Files\Internet Explorer\IEXPLORE.EXE" -nohome
to "C:\Program Files\Internet Explorer\iexplore.exe" -nohome
It will be fixed in a future DB2 version and Microsoft has been copied as well to see if this can be updated as a secondary measure.
Thanks,
Andrew
