7. Next copy either hppbp602.inf (if installing the PCL6 driver) or hppbps02.inf (if installing the
postscript driver) to the same location as the extracted driver files.

2605 series CD.
● Cause: The HP ToolboxFX is implemented using .NET technologies, and thus requires that the
Microsoft .NET Framework be installed on the users system. When the HP ToolboxFX software
installer runs, it will silently install Microsoft .NET Framework 1.1 (no service pack). This will allow
HP ToolboxFX to run, but there are some known issues with .NET Framework 1.1 (no service pack)
that might impact our customers.
NOTE
the HP ToolboxFX software installation, the framework will not be installed.
Solution: If the optimal system configuration is not set up on the users system, prior to or after the
HP ToolboxFX software install, the user might experience errors in HP ToolboxFX, due to defects
in various portions of the Microsoft code. Specifically, HP ToolboxFX might intermittently report
that it cannot connect to the device, with the error dialog shown above.
The optimal system configuration for HP ToolboxFX includes all of the following items:
● Microsoft .NET Framework 1.1 (no service pack) as installed by the HP ToolboxFX software
installer or by some other means.
●
Microsoft .NET Framework 1.1 Service Pack 1, available through Microsoft Windows Update.
●
Run Microsoft Windows Update until all critical updates have been downloaded and installed.
NOTE
any further critical updates.
These communication errors might go away if you reboot your computer, but the only way to
address this problem is to have the optimal system configuration described above. Another problem
has been observed if you happen to have Microsoft .NET Framework 2.0 installed on your system
at the time that you install the HP ToolboxFX software. The HP ToolboxFX software will still install
the .NET Framework 1.1, since HP ToolboxFX will not utilize the .NET 2.0 Framework (due to other
problems). After the installation, if you run Microsoft Windows update, it will not recognize that
the .NET 1.1 framework requires .NET 1.1 Service Pack 1, and might not get all of the necessary
security updates either. Again, in these cases, the user might experience the intermittent Cannot
connect to the device. error. The best recourse in this situation is to uninstall the Microsoft .NET
Framework 2.0, run Windows update repeatedly to get the .NET 1.1 Service Pack 1 and all of the
subsequent critical security updates installed, and then run Windows update and reinstall the .NET
Framework 2.0, which is available as an optional update.
Alternatively, if uninstalling the .NET 2.0 Framework is unacceptable, search the Internet for, and
then install the following Microsoft files:
● NDP1.1sp1-KB867460-X86.exe
●
NDP1.1sp1-KB886903-X86.exe
These files will not display as necessary options to the .NET 1.1 Framework if the .NET 2.0
Framework is installed. The Knowledge base article numbers to read are KB867460 and
KB886903, which are, respectively, Service Pack 1 for the .NET Framework and the current
security patch.
