Error loading NIVision.dll

[BASHBAM]

I have an application I have built with NIVision and Visual Basic 6.0. It runs fine on my development platform. It runs fine on the first platform we have deployed it on with the runtime engine. However on a second identical platform we are getting the error ERROR DESCRIPTION:Error loading NIVision.dll
ERROR NUMBER:31403

I have uninstalled NI Vision runtime and reinstalled. I have tried putting the .dll in the same subdirectory as the application. Nothing works! The odd thing is after the install the application worked briefly and then generated this error and now refuses to work and generates this error all the time. Any ideas? I hate to have to rebuild the OS but I am all out of any ideas as to why this stubbornly refuses to load this .d
ll. I especially want to aviod this as it is a remote platform! I have never seen this error before and have worked with this software for a couple of years now.

I agree, this is really strange. Especially since it seems to work with the other two systems. Have you tried a fourth system yet? To see if the problem is just this one machine? I did a search of our bug database, and didn't come up with any hits for that error number. I hate to say it, but you may need to rebuild that system. If the problem becomes more widespread- in that it shows up on other deployments, I would contact NI's Applications Engineers and talk to someone directly about the problem.

We have not tried on a fourth system and legally lack the required runtime licencse to do this.

I hate to say it, but we will indeed rebuild that system tomorrow, which involves a boat ride to a very remote site.

If this fixes the issue, which I am sure it will, then I will post that result to the site. If not I will be contacting an NI Engineer!

So frustrating!
