Office 2010x64 and external dll RRS feed

  • Question

  • Hi all,

    i have a little code, writed for office 2003x86, using a webservice and replacing some words in a word document.

    now, i have to migrate it to office2010x64. i've fisrt tested on office2010x86 (installed on a x64 2008r2) and it's always working fine, but now, with office x64 on x64 2008r2, i have an error: runtime eror '429' activeX component can't create object

    the dll is called from a macro in word with CreateObject("MyDll.SearchForm") and give the error. searchform is my main window

    the lib was registered with this command: RegAsm.exe MyLib.dll /tlb:MyLib.tlb /codebase

    the dll was compiled with neutral language (writed in

    so, anyone can explain why it's work with x86 and not with x64 and/or what can i do for resolve that

    thank's a lot (and sorry for my poor english)
