BEx Analyzer instalation

Hi all,

We installed SAP GUI 7.10 including BI and then found out that version of the Excel is 2002 SP2 which is not compatible, strange filter, chart and info buttons appears when I open query. So we uninstalled 7.10 and install 6.40. But when I check version of Analyzer it still shows previous release. Do you know how to get back to BEx analyzer based on SAP GUI 6.40?
