Excel won't open the file when I double click on it

I recently uninstalled microsoft office 2007 32 bit and then downloaded microsoft office 2010 64 bit.

When I click on my documents and then double click any file that is not an excel file it opens up.

When I click on my documents and then double click an excel file, the circle load symbol flashes for a split second then nothing happens.

If I open up excel, then click open, find the document I want and click on it, then it will open the file.

If I create a new file and save it as an excel file, then try to double click on it, it will not open.

If I create a new file and save it as a macro enabled workbook, then try to double click on it, it WILL open.

All of them are saved as .xlsx files.

When I right click and go to open with... there is no option to open the files with excel. When I browse for excel, I find the program and click open, excel won't go on the open with screen.

Any advice????
