Environment

Reflection Desktop (including Pro, for X, for IBM, or for UNIX and OpenVMS) 16.0 or 16.1

Situation

Reflection FTP Client (RFTPC.EXE) will crash in RNSocks.DLL when clicking on the Proxy Tab under the Security settings when running under Windows 7 or Windows 10 with App-V 5.x.  The FTP Client will not crash when installed with a Typical/Default installation on a real physical machine or a Virtual Microsoft Windows PC.

Here is the crash signature:

Resolution

Upgrade to Reflection Desktop 16.2 or higher to resolve this issue.

Workaround Steps:
Make sure the path to the Reflection FTP files is less than 128 characters.  With a typical install of the Reflection FTP client, the path will be something like "C:\Program Files (x86)\Micro Focus\Reflection", but with Microsoft App-V the path will typically be longer than 128 characters, which will cause this problem.

Cause

The problem is caused by the long (greater than 128 character) path name to the Reflection FTP DLL files and the install location of Reflection FTP Client.  Note the long path in the crash signature.  This is the type of long path which is created in an App-V environment as Microsoft App-V will typically install to a long path name greater than 128 characters which will cause problems with the Reflection FTP Client.
