Agilent34401的GPIB-ActiveX自动化问题

目的是通过GPIB远程控制四台仪器。
其中包括Agilent 34401 Dmm。
- Windows_7 64bit - 我使用的应用程序，使用Win-Wrap BASIC。
与Visual BASIC 6非常相似。（据我所知，应用程序是32位，不确定是否与问题有关） - 我使用的接口卡是Agilent 82350b PCI卡和最新版本的Agilent IO库
套件16.3 - 驱动程序：driver_ivicom_ivic_Agilent34401_1_2_2_0.msi）另外对仪器（范围，RFSigGen，SPECAN）罗德与安培各自IVI-COM驱动的其余部分;施瓦茨。
IVI类驱动程序也已安装。
仍然没有手中的仪器，我下载了Agilent34401_1_2_2_0.msi仪器专用驱动程序，只是为了尝试模拟，按照VBasic 6的IVI启动指南的说明构建一个简单的可互换程序.http：//www.ivifoundation.org
/downloads/IVI%20GSG%202011/IVI%20GSG%20VBasic6%202011.pdf *问题：*从代码的一开始，就不可能创建使用驱动程序实例，例如昏暗的OBJ时新Agilent34401错误
代码：ActiveX-Automation：服务器无法创建对象。
当我尝试从其他两个驱动程序RsRFSigGen和RsSpecAn创建实例时的情况相同。
直到现在：我已经尝试使用命令promt - > regsvr等来查看驱动程序是否已在注册表中注册。所有这些似乎都是有序的。
编程coleague更有经验也试图创建一些简单的脚本，但这里也出现了类似的问题。
显然，我使用了对驱动程序的.dll文件的必要引用。但是不确定64位或32位符号在这里是否有所不同。
请注意，我已经尝试引用.dll文件的各种组合。
我怀疑应用程序与驱动程序不兼容。
如果有人能给我一些建议，我将不胜感激。
提前致谢。



     以下为原文

  Objective is to remote control four instruments through GPIB. Among them an Agilent 34401 Dmm.

- Windows_7 64bit
- The aplication i use, uses Win-Wrap BASIC . Very similar to Visual BASIC 6.
    ( As far as i know the application is 32bit, not sure if has smthn to do with the problem)
- The interface card i use,  is an Agilent 82350b  PCI card and the latest version of Agilent IO Libraries Suite 16.3
- Drivers : driver_ivicom_ivic_Agilent34401_1_2_2_0.msi)
   In addition  for the rest of the instruments (Scope, RFSigGen, SpecAn) respective IVI-COM drivers from Rohde&Schwarz.
   IVI class drivers also installed.

Still not having the instruments in hand, i downloaded the Agilent34401_1_2_2_0.msi instrument specific driver just to try to simulate, building  a simple interchangeable program following the instructions from the  IVI geting started guide for VBasic 6.  
http://www.ivifoundation.org/downloads/IVI%20GSG%202011/IVI%20GSG%20VBasic6%202011.pdf


*The problem :*  From the very start of the code, it is impossible to create a driver instance using , for example the  

Dim Obj As New Agilent34401

error code :  ActiveX-Automation: Server cannot create object .   

Same situation when i try to create an instance from the other two drivers  RsRFSigGen  and  RsSpecAn.


Untill now:
I have tried to see if the driver is registered in the registry using command promt  -> regsvr etc.  All seem to be in order.  
A more experienced in programming coleague has tried to create some simple scripts too but similar problem occured here too.
Obviously i use the necessary references to the .dll files of the drivers  .Not sure though if the 64bit or 32bit sign makes a difference here and how.
Note that i've already tried to reference various combinations of .dll files.

I suspect application's incompatibility to the drivers.

I would be gratefull if someone could suggest me something .

Thanks in advance.
