distribute application with instrument control

[branislav.stupar@smsdatasystems.com]

HI,

I created CVI application for instrument control via GPIB card, and I would like to distribute it to other PCs in my lab that do not have complete  CVI installed on them.

Problem I have is that after I install it from distribution kit I made, I have two cases:

ON PCs that have installed complete CVI, it runs,

On PCs that have only CVI RTE, it can't run, because it breaks on commands that are controlling instrument.

Apllication runs normally on deelopment machine.

Could someone help me understand why, and what could I do to get it running on PCs without complete CVI on them? 

I am using CVI 7.1.0.

Hi,

I think the VISA-Runtime Engine is missing on the second PC. It´s on the device driver CD´s that shipped with your CVI or you can download it here:

This should help, best regards

Hi Alex,

Thanks, it works now.

I have overlooked to install visa run-time engine, and since  I installed ni488.2 ver 2.4 on those PCs I thought that should be enough....but it wasn't.

As an aside, CVI 8.0 allows you to build drivers and support components like the VISA runtime engine right into your distributions, so you can ensure that your installations contain everything they need to run without errors.  If this sounds useful to you, you may consider upgrading.

HI again,

Problems I had before are gone, but I am facing something strange during process of ditributing applications in my lab:

Sometimes (on some PCs) I must install both VISA driver for gpib card , and VISA RT engine, but sometimes only VISA driver without VISA RT.  I have only PCI GPIB for desktops and PCMCIA GPIB cards for laptops.

I find it very strange.

Mostly, I must additionally install VISA RT on laptops, while I do not have to do it on desktop PCs.

Could anyone explain me why is it like this,please?

I used VISA 2.4 and RT 2.5 so far. Is there any influence what version combination I use?
