I have also run into this issue. Trying to run a VI that uses BQ80xrw ActiveX component on other PCs typically causes labview to crash.
By installing the dev kit I have resolved the problem on one Windows10 PC a few weeks ago, however I am now unable to get it working on a second windows 10 PC. I can't think what I have done differently this time.
Also I was able to import the BQ80xRW control into the palette on the first PC but every time I try that on this second PC labview crashes.
I am running low on ideas. Anyone have further suggestions why labview keeps crashing when I try and do anything with this BQ80xRW control ?
