How to change path for Ev4Excel.xla

Dear All,

I'm trying to execute predefined BPF - custom menu (ProcessFunctions.xls). Whenever if click e.g. on Back, forward, open a file following similar message is being prompted:

Macro 'E:\Program Files\BPC\Ev4Excel.xla'!'EvMacroCall "OPENFILE","REPORTS\WIZARD\HotAnalysis\A01 Account Trend.xls","","","","","" can not be executed. Macro may not stated in this workbook or all macros can be deactivated.

Ev4Excel.xla is resided under path E\PC_MS.

How can I change path for macro call?

Or any other idea?

Regards,

Ender
