Under Windows 2008 - R2, error 87 (Invalid Arguments) is displayed when trying to install the signed version of the Amyuni Document Converter printer driver. This issue does not occur with the unsigned version of the printer driver. Some customers have reported the same issue on operating systems other than Windows 2008 - R2.
During installation the Microsoft certified printer driver, the Windows operating system copies and renames the amyuni.inf file and related printer driver files to the %system32%\DriverStore\FileRepository folder. Under some situations, Windows fails to copy the .inf file because of previous installations, mainly if the previous installation was for an unsigned printer driver. When installing a new version of the printer driver, the error 87 Invalid Parameters appears.
The event log shows the following consecutive errors:
Installing printer driver Amyuni Document Converter 450 failed, error code 0x3, HRESULT 0x80070057. See the event user data for context information.
Installing printer driver Amyuni Document Converter 450 failed, error code 0x0, HRESULT 0x80070057. See the event user data for context information.
Installing printer driver - failed, error code 0x57, HRESULT 0x80070057. See the event user data for context information.
The system needs to be cleaned up from previous installations in the DriverStore\FileRepository folder before attempting to reinstall the printer driver. The steps to clean up the repository are as follows:
- Open a command line window as an Administrator
- Run the command: pnputil -e. This command will list all the .inf files listed in the DriverStore, take note of all the .inf files where the manufacturer name is AMYUNI Technologies and the printer driver version is the one that you are trying to install. Ignore all inf files that do not point to the same driver version otherwise you will end up deleting earlier versions of the printer driver.
Published name : oem5.inf
Driver package provider : AMYUNI Technologies
Class : Printers
Driver date and version : 02/17/2012 184.108.40.206
Signer name : Microsoft Windows Hardware Compatibility Publisher
In this case, oem5.inf is the same as amyuni.inf but renamed by the operating system.
- Delete all the Document Converter inf files using the command: pnputil -f -d oemNNN.inf, NNN should be replaced by the value displayed by the pnputil –e command.
