Extensions\GenerateHttpUrl.WinSCPextension.ps1 in WinSCP installation folder.
So typically:
C:\Program Files (x86)\WinSCP\Extensions\GenerateHttpUrl.WinSCPextension.ps1
Though the file gets replaced on each upgrade.
So ideally, you create a copy of the file in your Documents folders and install it to WinSCP.

I am also getting this error recently.
Can you please tell me in which file should I change SetText to SetDataObject?
Thanks.

Restarting has no effect. I have no software the interacts with the clipboard. I stopped any programs or services that could have potentially interfered, such as VNC and AutoHotKey.

I have this SetDataObject workaround that works for me, but I thought I should let you know.

Thanks for your report. Does restart help to make the original version working? Do you have any software running/installed that may interfere with the clipboard?

I am attempting to use GenerateHttpUrl.WinSCPextension.ps1 for the first time. It keeps generating the following error:


I changed line 112 from:

to:

and it seems to work now. I wasn't able to find any other reference to this problem, but I thought you should know about it.

This is on Windows 7, WinSCP 5.17.10 (build 11087)
