I installed office pro plus 2010 on about 55 computers over the last two weeks. We have a volume license agreeement so unless I want to pay for tech support ms wont help me. Anyways on only one of the installs, whenever a .xlsx file is opened from the desktop it doesnt work. I can ope .xls just fine. I have tracked the problem down to the open with setup. for some reason inside the registry under .xlsx openwith it says excelcnv.exe instead of excel.exe. I tried every way to change this if i right click on the file choose open with and select excel it doesnt work. I have deleted the excelcnv.exe from the registry and it just gets repopulated as soon as the document is opened again. I even removed .xlsx completely from the registry. I tried again to open the file this time it just opens up the open with dialoge box. I choose excel from the list and boom go back into the registry and it says excelcnv.exe.
Any Ideas at Please Help
Thanks
