<p class="MsoNormal"><span style lang="EN">From our c# application, we are executing python (IronPython Version-2.7,
32-bit) scripts with the help of clrzmq (Version-2.2.5, 32-bit) for inter
process communication. From that python scripts we were trying to connect to
SSH using paramiko which is of 32-bit<span style>

<p class="MsoNormal"><span style lang="EN">We were able to run the python scripts from command prompt and connecting
to SSH without any issues, but when we try to run the same from our c#
application it is throwing us the following exception.</span></p>
