Windows 7 Professional registry errors?

Hi,
I have a pretty bad feeling about Windows 7. I can’t work with it. While logged in as an administrator, I try to register several *.ocx's in Windows 7 Pro and always get error code 0x8002801c. This is true, when using the Command Prompt method, using regsvr32. Now can anyone solve this problem? Please help me as soon as possible.
