Blue Prism 6.5.1 Running Slow/Nonresponsive After October Windows Patch

  • 1.  Blue Prism 6.5.1 Running Slow/Nonresponsive After October Windows Patch

    Posted 10-24-2019 20:56
    ​​Hello all,

    Has anyone experienced issues with Blue Prism running very slowly or hanging following that last Windows patch in October (I believe a second patch beyond the normal Windows Security Patch, an out-of-band browser update)?   The symptoms that occur are things such as a Reset takes about a minute to finish and Blue Prism becomes non-responsive for a minute or more (seems like forever when trying to get my work done).   Also, now a "Print driver host for applications" process will be found running under the Automate.exe process.   If that "Print driver" process is ended, Blue Prism will respond after about a minute and may work OK for an hour or so until this issue repeats.  

    It seems there may be issue with this patch:   One issue that may be related is: Applications and printer drivers that utilize the Windows JavaScript engine (jscript.dll) for processing print jobs may fail to behave as expected.   I wonder if this DLL is used by Blue Prism.

    Please share your experience if this is happening to you and your suggestions.
