EV3 mindstorm LAbview software always crash when open a project file

Johnny_Wang · ‎05-05-2019

Hi Everyone,

I am new here.

I am a profession programmer. I am instruct EV3 FFL team now.

I have a problem to open ev3 project using mindstorm LABView education version 1.4.2 (20180509.1)

it always crash, and throw this kind of exception:

Unhandled exception occurred at 2019-05-05_12-30-57-AM
System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.

but after my about 10 time try.( 30 minutes later ), it finally opened successfully.

I made some change , save it and close it .

the same thing happened when I re-open the file next time.

the below is my exception log.

I will attach my ev3 program and crash report.

Can anybody help me out ?

Thanks a lot

Johnny Wang

Did you try to make a Force Reinstall?

Have you tried to contact Lego Support or National Instruments support?

Thanks a lot.

I will give it a try.

I report a defect of labview ,

https://forums.ni.com/t5/LabVIEW-for-LEGO-MINDSTORMS-and/EV3-mindstorm-LAbview-software-always-crash...

can any developer have a look ?

The bad thing is the application just crash without provide any useful information for me to troubleshooting.

thols · ‎05-10-2019

Have you tried the suggested solutions in that thread? Have you tried installing on another PC? Something is probably corrupt with the installation.

Johnny_Wang · ‎05-12-2019

Thanks a lot for above replies.

I tried all solution you guys suggested. run ev3 program on different machine and clean reinstall the software.

I also sent email to Lego support team.

They told me the software EV3 software student edition is different from LABView software.

occasionally I opened the program , after I made some changes,

it suddenly crashed again.

Based on my observation, I feel the link on block especially on switch/loop block overlapped. that will cause EV3 software cannot recognize the work flow of the program.

anyway, I think EV3 software is not robust enough to handle all the situation in block programming.

Johnny_Wang · ‎05-12-2019

Hi All,

Finally I think I found the root cause why the EV3 software keep crashing.

It just cannot handle a little big program.

I was inspired by one post online said EV3 software is not good for many tabs opened in software.

I watched the software , the size of my code is 197KB , it turns on occupied 850MB memory when it try to compile the program. that cause Ev3 software crashed . even my computer has 16GB memory, and memory usage is only 30%.

It finally can be opened correctly when I reduce the inactive code and reduce my file size to 180KB. it occupied about 750MB.

the program can be opened consistantly.

I hope this can help other guys.
