OK, it's fixed now. It was LabVIEW 64 bit compatibility.

I guess you learned the hard way one of the biggest reasons why LabVIEW 64-bit isn't recommended unless you have a specific reason why you need it - i.e., need a lot of memory.

 

Did you have LV 32-bit installed first?  If so, probably re-installing the drivers would've worked.  But if I were you, I'd abandon that line of thinking and just stick with LV 32-bit.

I didn't know it wasn't recommended. No, I had never installed 32 bit.

Unfortunately, it's not common knowledge, but it's very nature - being 64-bit - just about everything that it uses must be 64-bit, too.  That's not just a labVIEW requirement; it's Windows that makes such restrictions.  Notice, for example, 64-bit browsers have a lot less third-party support - except where the third party has specifically introduced a 64-bit counterpart to its 32-bit plugin.

 

So that means if you use 64-bit LV all the dlls that you'll be using, including any intrument drivers, must be 64-bit also.  Oftentimes a vendor will only have a 32-bit dll for their equipment.  I've even had vendors send me the source code to recompile it as 64-bit driver before if it wasn't something they were actively supporting any more.

 

I hope your project is going forward smoothly now.  🙂
