We are migrating from XP to W7 Enterprise 64bits.
As printers we use Konica Minolta C353/C203 copy-machines.

On XP we use Printer Driver Profile to configure printer automatic and want to continue using this. The problem is that i can't create PDP in W7. It says only:
Error: Creating Printer Driver Profile Failure
Error occoured configuring driver.

iPrint Manager and Broker is running on NW6.5 SP8 with newst iPrint Patch.
iPrint Client 5.56

I run IE8 64bits as Administrator.

Uploading drivers and installing printer works perfect, but only PDP doesn't work on W7 64bits.
