If this error comes up when you first sign on, see if you can disable that file from startup. Click Start > Run > Type "MSCONFIG" ... Click the startup tab and look for a program that is using attrhon.dll or something similiar. Also, check your services and see if anything related to that program is running. Can you just delete that file?
I have a Sony Vaio. Recently, I removed some programs in an effort to free up more space on the C drive. There is a C and D drive on the computer, but almost nothing is on the D drive.
Since that time, I have had an DLL error:
C:\Users\Mom\AppData\Local\Temp\attrhone.dll is not a valid Win32 application.
I have tried to find this folder but it does not exist.
I would appreciate any help.
