I have just upgraded my Windows Vista machine to Windows 7 and have seen that there is something wrong with the Microsoft Excel. Actually the excel files that I have created through Excel 2000 while I was using the Vista OS on my machine, are showing some error after trying to open them. When I try to save them then it shows the following:
"An unexpected error occurred, Not enough Memory available to complete the operation. Close other programs to make more Memory available and then try again".
