My 32 bit app works fine on 32-bit OS with SalesLogix.

But the same app won't be able to create SalesLogix component on 64 bit OS. Is it because SalesLogix version is also 64-bit version? Is there a way to have 32-bit SalesLogix COM installed on 64-bit OS?

You need to set the compile mode to x86 only.

Do you my app's compile mode? I think it is set for x86. It is old VB6 app.

SLX is only 32bit - so 32bit +32bit should be fine - how are you establishing a connection ?

On the Compile tab - click Advanced options, on the TargetCPU change from anyCPU to x86.

On VB6, there is not target option.

The app uses the following to connect to SalesLogix component:

        Set SLX = CreateObject("SalesLogix.ClientObjix")

BTW, do you mean SalesLogix is a 32-bit app (at least, its COM components) even on 64 bit OS?

Ah right, I see - it's not actually a connection but a COM component. Hmm, not sure about that, I would say not though.

SLX is a 32 bit app......even on a 64 bit OS....

It depends on where the script is running (or actually *how* it is running). There are two script interpreters on a 64-bit machine. A 32-bit one and a 64-bit one. If the script is being interpreted by the 64-bit script interpreter, it CAN'T create a 32-bit COM object using CreateObject. It's just not possible. You must run the script with the 32-bit script interpreter in order to see or use a 32-bit COM object. SalesLogix is a 32-bit app always, even on a 64-bit machine. 

See this article for more on the 32 & 64 bit interpreters: http://blogs.msdn.com/b/helloworld/archive/2007/12/12/activex-component-can-t-create-object-when-creating-a-32-com-object-in-a-64-bit-machine.aspx

Thanks for the information. I'll check around more on the problem pc to make sure.
