Enhanced driver signing beginning with ver 6.60 of InstaCal / Universal Library


Beginning with InstaCal / Universal Library version 6.60, MCC has enhanced its driver signing (SHA-256).   If you are installing on Win7-32 or Win7-64, and if your Windows 7 is not up-to-date, we recommend that you fully run Windows Update prior to installation.   Attention Vista-64 users:   Vista-64 cannot verify the new drivers, and since disabling driver verification is only possible temporarily (invalid after each reboot), we recommend that you either install an older version of InstaCal/UL (namely 6.55), or migrate to a newer Windows version.
