Hello guys, is there a way to access some kind of Microstation log when user encounters MDL loader error "OS could not load xx.dll" (error 127) ? Or do I need to manually find out with applications like ProcessMonitor? I was wondering, maybe Microstation keeps more detailed logs somewhere. I talk now about V8I version, but i suppose CONNECT has the same mechanism.
Thanks for the help
Hi Lubo, this is likely to be a version mismatch between the MDL and MicroStation.
Which MDL is involved (or is it more than one)?
When do you see the error?
I'm assuming this is appearing in a black text window?
Which version of MicroStation?
Regards
Marc
Hello, this error is caused when I try to load my own plugin .ma file. The error displays at the start of the microstation. Yes, it appears in console window (so thats why i was wondering if MS keeps some kind of logs which could describe it more properly). Version of MS is kinda old one, MicroStation V8i SS4 08.11.09.867. I mean, the plugin works on other machines but this is a new clean install machine which displays the error, and as I dont have access to the machine its kinda troublesome to troubleshoot this problem. Thats why some more accurate log would come in handy in these situations. I thought reinstall of MS would help but it didn't.

Because "MDL" is too fuzzy term with several different meanings: What is "type" of .ma application? Is it old pseudocode application (no dll, only .ma + rsc files), or is it native application (.ma loader + dll files)?

Are versions (MicroStation, Windows as well) the same?
Often, even when probably not this case, different behavior is caused by missing libraries (like C runtime / msvcrt.dll).

The problem is that it's internal MicroStation error, not Windows one. Maybe to use debugger (e.g. WinDbg) and to attach to the process, can be tried.

One more idea:

If the application is native code application, I recommend to check all expected depdencies. Some "dependency walker" (like this one) can help to analyze whether all necessary dll (libraries) are available. But what can be tricky is when dlls are in different folders and MicroStation or Windows setting is involved in the dependency resolution.
Regards,
Its plugin .ma consisting also of DLL. I sent DependencyWalker app to client and asked them to send me a screenshot, but it looked fine(even though as u said, its kinda tricky when DLLs are not in same folder). I hope Process Monitor log will tell me more.

Well actually i havent thought about Windows version. Because i didn't try it on windows 11 yet.
