Have you restarted the system? and run the install setup?

if the error still appears, then

take a registry backup

1) Open registry and go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

hight light Session Manager on the right hand side delete the value PendingFileRenameOperations

2) Also delete the same value from

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet001\Control\Session Manager\PendingFileRenameOperations

and then run the install file.

Hi, pete_4u2002,

Before install SEP I edit registry I know this problem.
But problem with install remained.

I try cleanwipe and restart server, install sep and I will look to new install log¨.

Thank you

Hi,

Server is DC

Thank you

Hi,

and new log from other server win2008 R2 Domain controller.

Thank you

did you try disabling the UAC and installing the SEP?

YES ,UAC disable, install mstsc/admin

Hi;

Can you please try to run setup " run as adminitrator"

And also can you please try to do following.

Create an install package or create a custom setting under the “Client Install Settings” options to not use “Add the program to the Start Menu”, leave this unchecked.

If the install is successful, manually create the shortcut on the desktop that points SymCorpUI.exe

- And try to search symantec on the registry and delete all the findings if SEP is the only symantec product on your server.

Hi ,

I tried install new configuration package without Add the program to the Start menu.

I tried mstsc /admin, disable UAC, run as administrator, install version SEP 12.1.RU 1 MP1 and SEP 12.1 RU 1 - problem with install script

Thank you
