Thanks for your report.

Can you send me an email, so I can send you back a development version of WinSCP for testing? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

I get the following error on Windows 10 when installing via the system account or SCCM "Failed to expand shell folder constant “userprograms” - “SHGetFolderPath failed with code 0x80070002"

This error only happens when installing with the System account or SCCM the first 2 times on Windows 10. If install with just the administrators account it doesn’t happen at all. In addition,
SHGetFolderPath has been a deprecated function since Windows Vista.

Thank you for the suggestion. I saw this post, but Windows 7 doesn't have the same issues as Windows XP.

I actually solved the issues late yesterday. The shell folder for my desktop was updated with a mapped drive reference. I had to update the reference to a fully qualified/UNC reference. I was able to install the WinSCP client.

Would this help?

I am trying to install WinSCP version 5.1.7 on a Windows 7 Enterprise HP laptop. I have selected the default installation settings and receive the following error: Internal error: Failed to expand shell folder constant "userdesktop". My Desktop, Favorites and Personal/Documents directories are on a network drive. I have updated the registry entries, but I still receive the error.

Here is the log file from my last install attempt:
