LabWindows/CVI

[PeggyC]

Hi,

I am using CVI 2009 Full Development Environment, and I am having problem in launching the application.  I can see the flash screen in application starts up, but the screen would just disappear.  There was no error message or any type of dialog prompt.  When I tried to invoke the CVI from TestStand, and that returns the following error message:

Unable to launch CVI

Error Code: -17701

I wonder if anyone had similar situation?  And how to resolve?

Thank you.

Peggy

I made a search in the Knowledgebase and found this entry: hope it can be of some help to you.

Thanks for that good find, Roberto. Let us know if that doesn't fix the issue, and we can look into it further.

Hey Peggy -

If this is still giving you trouble, I'd recommend looking at the workaround in this LabWindows/CVI 2009 known issue - it sounds very similar based on your description.

That fix for corrupted registry sounds like a possible solution, but I have already reimaged the drive and re-installed the software.

Thank you for the hints.

Hi,  I guess I shouldn't say the problem went away... Because the CVI refuses to come up again.   I tried the procedure defined in the Known Issue, and I stock at the first step:

Launch Start>>All Programs>>National Instruments>>LabWindows/CVI 2009>>Tools>>Import-Export Settings

The error message that returned to me says: The buffer passed was too small for the operation.

Beside the procedure in Known Issue, I also tried to reinstall the LabWindows/CVI, which it also doesn't work.

Were you able to try deleting the registry key directly as noted in the Known Issue workaround?? The Import-Export Settings tool would simply be deleting those keys for you, so a direct approach may be better in this situation.

Nick,

You're the man! Deleting the registry key fixed this problem for my customer.

After a few months of not developing any new CVI code, I was working on a couple of new functions I call from Teststand and I am getting the same error mentioned above, Error Code: -17701 Unable to launch CVI, when I set TestStands CVI adaptor to run an external instance for me to single step the function I wrote.  I have done this many times before on this setup and never had this problem.

I am running TestStand 2010 SP1 with CVI 2010 on Windows 7.

I tried to look at the Knowledge Base Link mentioned in this thread about removing a registery key, but the link does not seem to be valid anymore.

Thanks,

Pete
