SAP GUI 7.10

Hi BI Guru,

In GUI 7.10 for BEx analyzer iam gettng this error ...

"sapfhook.dll is a BW 1.2B component which should be deinstalled before the BW 2.0A is installed. For that reason the file should not exist on the PC. Unregister sapfhook.dll with Start/Run "regsvr32.exe /U SAPDestDir\sapgui\%4" and delete %5 in %6 with the Windows Explorer."

Can someone will help me out for this....

The directories are their in thier respective folders

thanks
