I am in upgrade phase BI7.0->BI7.31 on Win/Mssql. I am in phase SUBMOD_SWITCH_KERNEL/KX_SWITCH

During this phase in module MAIN_SWITCH / Downtime I: Switch tables and Kernel I got error message: "Deleting 'K:\usr\sap\BIU\DVEBMGS00\exe\sapevents.dll' failed: Access is denied."

I got explanation of that error in note "Note 1790828 - Central Note -
Software Update Manager 1.0 SP08 [lmt_004]
" which leaded me to note: "Note 1556113 - sapevents.dll in
DIR_CT_RUN is locked

However HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\eventlog\Application\SAPBIU_00 value of "EventMessageFile" already contains


I then renamed the K:\usr\sap\BIU\DVEBMGS00\exe\sapevents.dll to K:\usr\sap\BIU\DVEBMGS00\exe\sapevents.dll.old but when retrying upgrade encountered "again" message: "Deleting 'K:\usr\sap\BIU\DVEBMGS00\exe\sapevents.dll.old' failed: Access is denied."

Last idea is to restart the machine but can I do it in Downtime phases?

What would you suggest?

thank you in advance

    Delete or move all the files in the K:\usr\sap\BIU\DVEBMGS00\exe location to another place.

    Keep this directory empty.

    If you are unable to move or delete the files from K:\usr\sap\BIU\DVEBMGS00\exe then stop the SAP services from services.msc and then do it.

    Once done start the services and then continue with the upgrade.

    • Hello Jan

      As this is a Windows system there will be services related to SAP in services.msc

      Start - Run - services.msc - Enter

      Check the status of the SAP related services. Are they stopped or running ?

      Make sure you close the MMC console as well.

      If nothing is helping you in deleting those files then restart the server and then delete the files and start the SUM tool and repeat the step.
