I am familiar with the process and instructions on how to unload the analysis
toolpak. However, when I follow the instructions, I get the following error
message: Microsoft Office Excell cant run this add-in. This feature is not
currently installed. Would you like to install it now?

Upon selecting yes, I get the following error message:

Microsoft Office Excel cannot access the file 'analys32.xll' There are
several possible reasons. -The file name or path does not exist, -The file is
being used by another program, -The workbook you are trying to save has the
same as a currently open book.

Please help me with this problem. Thanks
