TH3800.dll loading causes "Invalid access to memory location".

[SimonGoodson]

Hello, back again.

I'm writing a thermotron temperature control program for a school project and I'm having an issue with the drivers supplied by Thermotron. I unpacked their drivers and put them in the instr.lib folder, then I put the included TH3800.dll into C:\VXIpnp\WinNT\bin in accordance with directions. I'm using the Student Edition of LabVIEW 2010 with SP1, and every time I load a VI from the library I get an error message that says:

Error loading "TH3800.dll".
Invalid access to memory location.

I have no idea what the problem is exactly, and am not sure what to do to fix it. Any suggestions would be appreciated.

Thanks,

Simon

I'm not positive, but it seems like either the drivers you have are corrupt, don't exist, or are locked in memory somehow. This would definitely be an issue you'd want to bring up with Thermotron as they'll have more details about their DLLs. I tried googling about it and the dll name it's self brings up shockingly little information. Definitely something worth talking to them about!

Thanks, I thought this might be the case, but I'm pretty new to LV, so I wasn't sure if maybe I was missing something. Thanks for the reply.
