Can`t open excel files by clicking on the file icon?

Hello.
When I try to open excel file by clicking on the file icon I get the next message:”There was a problem sending the command to the program”. But if I open the file under Excel – Open, it opens fine.
I read some topics describing the similar problems, but I found the same error only relating to Word. I tried open and repair function, disabled all add-ins as it advised at one forum. Even reinstall Office 2007, but nothing change. Can somebody help me in my issue?
