I've upgrade office 2007 to office 2010
After the upgrade i am unable to open any .xlsx files using excel
I have a number of .xlsx files on my desktop and windows doesn't know which program to use to open them. If i open excel first and go to open and then point to the files, they open fine, just not when i double click on the files directly.
If i create and save a new excel spreadsheet in the default settings as .xlsx it saves it fine but then doesn't know which program to open it in.
This is only happening in Excel, Word files are fine.
I'm using Windows 7
I believe this to be registry related issue.
So, it should be possible to use Registry to fix it. You could try using regedit. 1.Click on the "Start" button, and then click on "Run." In the dialog box that appears, type "regedit" into the text box, and then click the "OK" button.2.Navigate to HKEY_CLASSES_ROOT\Applications\EXCEL.EXE\shell\open\command3. change to Office14.
In case the above does not work for you, here are a couple of related resources containing more fix options: 1) http://answers.microsoft.com/en-us/office/forum/office_2010-excel/excel-troubles-xlsx-files-just-wont-open-on-double/2828f328-13ba-48cf-a0b8-fb8a927c 71e5?page=22) https://community.spiceworks.com/topic/246692-excel-2010-can-t-open-xlsx-files-only-xls3) Excel 2013 Pro won't open files when double -clicking the file.
Please let me know how these suggestions work for you.
