Application builder DLL 6.1 crashes

[Richard2950]

I have a Win98 machine that has Microsoft Visual C++ 6.0, and I have a LabVIEW 6.0.2 DLL that I call. LabVIEW is installed on a separate Win98 computer. This has been working fine for over a year. I made a minor change to the LabVIEW vi (I added some entries to a text ring) and generated a new DLL. Since I am now running LV 6.1, I got a DLL that was incompatible with the other system. When I installed the LV 6.1 runtime system on the target machine, I started to get crashes in LVRT.DLL. I uninstalled and reinstalled a couple of times, but got the same behavior. I went back to the 6.0.2 runtime system and my old DLL, and everything is fine (except my text ring doesn't have the entries I want). Any suggestions as to where the problem lie
s and how to solve it?

I tried it again today, and now it works. This time I installed the 6.1 runtime engine before uninstalling the 6.0.2 version. I also made sure that all of the .h files were replaced with new versions before re-compiling my C++ program. I don't know what made the difference, but I am happy now.

Updating the runtime engine is what solved your problem
