Issue
During statup, a "Error occurred during the validation of this file" warning message appears, relating to the 'KSC_Database', typically after a new installation of KeySCAPE or a Windows update, where the Microsoft 2010 Access Driver has failed to install or run correctly.
Solution
- With Microsoft Office and KeySCAPE installed, make sure none of the associated programs are running
- From Control Panel > Programs and Features, find and uninstall "Microsoft Access database engine"
- Download and install the Access Database Engine x64, which available from our download page linked here.
IMPORTANT
You will need to install this as a local administrator (right-click > Run as Administrator). If you do not, it might appear to have installed but has not because it has silently failed.
Note: To resolve this issue in the long term, it is recommended that your install the 64-bit edition of Office.
