msi need Admin rights to installSolved

Hello,

i try to install nessus Agent on the client. The Agent needs Admin rights to get installed. I need some batch file for starting the installation because there are some arguments got with.The batch file:[msiexec /l* nessuinstalllog.txt /i %wu-temp%NessusAgent-7.7.0-x64.msi NESSUS_SERVER="nessusagent.foobar.at:8834" NESSUS_CA_PATH="%wu-temp%RootCA.cer" NESSUS_KEY=280ba0f /qn]

the update should be called with windows task scheduler (highest permission) [wyupdater.exe /fromservice]when i call it by hand, i see the temporary folder is created and the files get download. 2-4 seconds later the folder will be deleted. in the msiexec log i see some " Error 1925 You do not have sufficient privileges to complete this installation for all users of the machine. Log on as administrator and then retry this installation"in wyBuild i setup the batch with elevated rights. when i run the update via cmd the UAC is comming up. What did i wrong?Thank you
