DAQFactory Error when changing versions


Recommended Posts


I have several versions of DF on my hardrive, from 5.40 to 5.87, I have several installations that require them.

Recently when I try to open version 5.85 just after modifiying a document on 5.86 I get this message (see attached).

So far the only way around it is to re-install 5.85.

What is causing this? how to avoid it?

The DAQConnect dll is causing this. 5.86 uses a different version of this DLL and overwrote your 5.85 (and previous) version, basically killing 5.85. The solution is to remove the file (DAQConnector.dll) from your system folder and put the appropriate version in the appropriate DAQFactory directory.
