LogicAnalyzer software crashing on Win10

[thisisgregm]

LogicAnalyzer software crashing on Win10.

Latest win64 version 2.1.0.0.

Steps to replicate:

• Open Logic Analyzer software
• Open serial device, it reports itself as LOGIC_ANALYZER_V1_0
• Click Capture
• Choose any settings, for example capture CH01, trigger CH01
• Press Accept
• it waits a few seconds then crash

Tried to open it from a command line to see some errors, but nothing is reported.

How can I debug it and see some errors please?

Not 100% sure if it's an app or my permissions in Windows or a space in a program path ("C:\Program Files\LogicAnalyzer"). Can someone please confirm if they have the same problem? If not I'll look elsewhere (Windows)

Hi.

I have tested with the latest uploaded version of the software and firmware using a path with spaces and I'm unable to reproduce the problem.

About permissions, you should not need any extra permission, no need to be admin or authorize the app, it doesn't needs elevated privileges.

You can check the windows event log, there should be some info about the problem. Also, if you have VS2022 the best is to download the source code and run it directly from Visual Studio, that will show you exactly where the error happens.

Do the crash give you any information or it simply closes the application?

It just closes by itself with no info given.

At work I think we have Panda antivir running. I had to ask IT admin to whitelist dll libraries to make the software running as I had errors reported by Panda. Now no reports from Panda, so I don't think the problem is here.

Will take Pico home and try it on a home PC.

I'll report back, but I guess it would be too obvious it it happens due to a software bug. Nobody reported similar issue before, Seems like it's my Windows. Will try to see the error log to check if it's anything there.

checked windows Log and have some weird entries there:

Access to the path is denied sorted by running it as an administrator (that's probably our work windows policy, will speak to the IT admin). However the path from other lines C:\Users\geniw\source\repos\LogicAnalyzer\LogicAnalyzer\ is definitely not correct (I don't have geniw user on my computer).

Other entries in the error log are:

As I said managed to run it as admin with no errors, so please confirm this is my OS problem (if you think it is) and I'll close the issue here.

Ok, the path that you see is not incorrect, that's where the program was compiled and that info is embedded as metadata into the assembly to make it easier to debug any problem.

And yes, the problem is your machine, the path where you have stored the application has restricted permissions and the app cannot read/write files from it. If you move it to another folder that does not have restricted permissions it will work.

Cheers.

Thank you!
