It looks like you are running java 8, but are using some libraries from java 7.

[HowardAbraham]

I uninstalled Java and reinstalled it and got the same result.

Are you saying the hardware simulator requires version 7 of Java?

[cadet1620]

Works with Java8 on Win7 for me

Google search for "java msvcr100.dll crash 0x121f4" turns up this bug report
    https://bugs.openjdk.java.net/browse/JDK-8178873
and several other reports of this crash happening with other apps.

Since this is FileChooser related it may be a startup path problem.  In the past there have been problems with old information in the *.dat files in nand2tetris/tools/bin.  (They keep track of the last oppend directory for the tools)

You might try deleting "Hardware Simulator.dat" and reruning HardwareSimulator.

I was referring to this:

CLASSPATH=.;C:\Program Files (x86)\Java\jre7\lib\ext\QTJava.zip

I'm not sure what it is for, but my guess is that it may cause problems because it seems to be for java 7.

[HowardAbraham]

I removed that from the java_class_path and renamed that directory for an added measure of prevention, but that did not solve the problem.

[HowardAbraham]

The only DAT file I have is Virtual Machine Emulator.dat.  Renaming this file had no effect.

What can be a possible solution for this?
