'WinSCP process terminated with exit code -1073741819 (C0000005). There was no output. Response log file C:\Users\xxx\AppData\Local\Temp\wscp1044.01EA0A2F.tmp was not created. This could indicate lack of write permissions to the log folder or problems starting WinSCP itself.'
I Googled the error and just found the recommendation that I should be using the latest version of WinSCP, which I do. I'm able to run the WinCP exe without any problems. Any helpful information beyond "be sure you have the latest version" would be appreciated.
