Repeated crash on Win7 64-bit; is version 4.5 real?

Repeated crash on Win7 64-bit; is version 4.5 real?

Repeated crash on Win7 64-bit; is version 4.5 real?

(OP)
I installed OpenFTA version 2 on Windows 7 64-bit. I can draw a fault tree, define Primary Events, and associate each basic event with a Primary Event. However, when I try to validate or create minimal cut sets, the application crashes without any error messages. The log file always says the same thing:

% An unexpected exception has been detected in native code outside
% the VM.
%
% Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005)
% occurred at PC=0x77AEE3C6
%
% Function=RtlInitUnicodeString+0x196
% Library=C:\Windows\SysWOW64\ntdll.dll
%
% Current Java thread:
% at sun.awt.windows.WWindowPeer._setTitle(Native Method)
% <...snip large dump...>

This does not happen when I run OpenFTA on the accompanying example files. However, I noted that the syntax of the example *.fta files differ signficantly *.fta files created from scratch.

Has anyone successfully used OpenFTA recently on a modern windows platform e.g. Windows 7 64-bit? Were you operating in a locked down environment without administrator rights?

I noticed that there is an OpenFTA 4.5 at http://www.fileguru.com/OpenFTA/info. It's actually a pretty big deal for me to get things installed and test drive it for a few days. I'm wondering if it's a repackaing of the same version as the one I got from http://www.openfta.com. After all, there was no further development on OpenFTA, so how could the version jump from 2 to 4.5? Also, that site seems full of misleading links to other-ware, so I'm leery of spending time chasing down that rabbit hole.

RE: Repeated crash on Win7 64-bit; is version 4.5 real?

I've tried. The OpenFTA forum is basically a graveyard. OpenFTA is provided to the public explicitly without support. The mechanisms for my shop to get consultation are...well, they make it extremely impractical. This is pretty well the only avenue for getting answers from others who may have used OpenFTA (it's a big "if" however, due to the age of the application).

RE: Repeated crash on Win7 64-bit; is version 4.5 real?

(OP)
I hope the fact that I'm also posting solutions that may help other users of this app (if they still exist) makes it more acceptable to post to this forum.

Along these lines, I think I might have found the cause of the problem. When I installed OpenFTA on a different machine with an administrator account, I was able to create a tree from scratch, validate, and generate minimal cut sets. So the problem might be one of the following: (i) I need ownership of the OpenFTA intall directories, or (ii) I need admin rights.

Mind you, the machine that I had an administrator account on was an XP machine, whereas the one on which OpenFTA kept crashing was a Windows 7 64-bit machine. So it is possible that the cause is also related to the use of Windows 7 and/or 64-bits.
