We haven't got any crash report. It seems like crash reports are broken as well :). I will check it.
Can you post the following files?
%TEMP%/omeditcommunication.log
%TEMP%/omeditcommands.mos
%TEMP%/openmodelica.stacktrace.OMEdit

I looked a bit into this.
We do: omdevPath = Util.makeValueOrDefault(System.readEnv,"OMDEV","");
and if OMDEV is not present I guess we get a crash. And yes, via cmd.exe

> cd \Path\to\OMEdit.exe
> set OMDEV=
> .\OMEdit

will reproduce the issue.
We have

extern const char* System_readEnv(const char *envname)
{
  char *envvalue = getenv(envname);
  if (envvalue == NULL) MMC_THROW();
  return strcpy(ModelicaAllocateString(strlen(envvalue)),envvalue);
}

which means that if the env variable does not exist we do a throw and die because we don't do
MMC_TRY_TOP_INTERNAL for omc_Main_setWindowsPaths.

Adeel, can you wrap the call to omc_Main_setWindowsPaths within a try catch block?
Then try to see if it works by un-setting OMDEV variable.

Fixed in r25813.

It doesn't make sense to keep closed ticket in the "Future" milestone that were simply forgotten to assign to the correct milestone in the past.

Removing the pre1.9.4 milestone in favor of 1.9.4.
