The batch scanning utility within Slate, known as Batch Acquire, is a process that is highly dependent upon local factors, including the scanner hardware, the scanner drivers, the .NET Framework version installed, anti-virus software installed, the network user account, domain group policies, memory availability, corruption of the local application cache, and a host of other factors. These many factors may manifest themselves in similar ways, which makes troubleshooting Batch Acquire issues a process which requires a multi-pronged approach. Since our ability to troubleshoot local equipment is limited, we recommend working with your institutional IT resources to troubleshoot any errors you may be receiving using the resources below.
If difficulties persist with any local equipment configurations, we recommend scanning any documents to your local computer/network using your scanner's native interface. These PDF documents can then be uploaded to Slate digitally in a batch via Batch Acquire, or individually on a person record interface.
Important
Microsoft ended Mainstream support for Windows 7 in January 2015 and Windows 8 in January 2018 and therefore will no longer supply non-security updates for either of these operating systems, to either the TWAIN or .NET Framework upon which Slate Acquire is based. Therefore if the error/issue should persist after following the instructions outlined, it may be necessary to upgrade to Windows 10.Specific Error Messages
If the error is limited to a specific user on a specific workstation, this likely indicates corruption of the local application cache which will need to be reset.
Open a command prompt and run the following commands:
rundll32 dfshim CleanOnlineAppCache
rmdir /s %localappdata%\apps\2.0
If an "Access is denied" message appears, reboot the computer and then open a command prompt immediately upon restarting (prior to accessing Slate) to ensure that there are no files actively in use.
This error message is typically caused by an error in either the Microsoft TWAIN system or .NET Framework as it's trying to pass data from the scanner driver to the Slate Acquire software. As the error originates from the Operating System the solution will depend upon the specific circumstances.
Operating System or Software | Steps |
---|---|
Windows 7 and 8 operating systems |
On Windows 7 and 8 operating systems, it may be necessary to repair the Windows Update installation and apply any outstanding system updates.
|
Windows 7 SP 1 systems |
For some Windows 7 SP 1 systems the following updates may need to be applied manually:

Fujitsu scanner and the PaperStream IP scanning software |
Systems using a Fujitsu scanner and the PaperStream IP scanning software may experience this error when selecting a non-Custom Scanner Preset in the New Material dialog box. To test this:

This error message is due to an error in the configuration of the .NET Framework. Please follow the instructions for repairing and resetting the .NET Framework. If this should fail to resolve the situation, and within the details of this error the message of "A call to SSPI failed, see inner exception. ---> The requested security package does not exist" appears, it may be necessary to edit the registry to explicitly enable them.

To ensure that there aren't any driver issues and to reset the TWAIN system, we recommend resetting the drivers for the imaging device.
We also recommend ensuring that the latest version of the .NET Framework is installed on the computer, and in some very rare cases this might require either repairing or resetting the Microsoft .NET Framework. Please contact the organization's local IT support with any difficulties during these steps.
