pedrv.sys not comatible with this system

  • I have been troubleshooting an issue with backup software and found that upon startup every morning, the event logger reports these errors:

    "The P&E Microcomputer Systems PCI driver service failed to start due to the following error: This driver has been blocked from loading.

    Followed by,

    \systemroot]\syswow64\drivers\pedrv.sys has been blocked from loading due to an incompatibility with this system. Please contact your software vendor for a compatible version of the driver.

    I am running a 64 bit Windows 7 machine. I believe the driver was installed when I loaded the software for an old P&E Microsystems parallel port BDM. Is there a later driver for 64 bit machines?



  • Parallel port does not work on 64-bit machines.

    • I have a pci card in my machine with a bi-directional parallel port, which is probably why the message states .... PCI driver....
