my problem looks like those described in some of the previous threads
about Vista except that the workarounds do not seem to work. Environment :
- iprint server on Netware 6.5 SP7 with latest patches, including Apache
2.0.63 and iprntnw65sp7a.zip.
- Windows Vista x64 (in french), SP1, Novell client up to date.
- a few Vista 64 drivers have been installed on the server via iManager
2.7 for Xerox or Lexmark machines.

With IE "standard" (32 bits), the 64 bits nature of Vista is well
recognized and the corresponding iPrint client installs well. That is
not the case with Firefox, which proposes only the 32 bits client.

The problem arises later : when we want to install a printer, the
install begins but stops on a 1797 Windows error code ("unknown printer
driver"). What can we do for this ?
