SyncToy 2.1 (x64) Won’t Install On Windows 10 (Solved)

This blog post tells you how I installed SyncToy 2.1 (x64) on Windows 10 Pro 64-bit.

The issue:
I already had Microsoft .NET Framework 4.7.2 installed, so when I ran SyncToySetupPackage_v21_x64.exe, I was surprised that I saw the following:

This setup requires the .NET Framework version 2.0.50727. Please install the .NET Framework and run this setup again. The NET Framework can be obtained from the web. Would you like to do this now?

I selected, yes, but ended up with a 502 Bad Gateway error message. Luckily the problem is easily resolved.

Here is what I did to solve the problem on my 64-bit computer:

1. I downloaded the Microsoft .NET Framework Version 2.0 Redistributable Package (x64).
2. I ran the install application, saw the screenshot below and selected ‘Download and install this feature’.
3. I selected ‘Close’ once the .NET Framework 3.5 had been installed.

Installing SyncToy 2.1 (x64)

1. I had already downloaded the program. I ran the SyncToy 2.1 (x64) setup application. I read the text shown to me. I then clicked on the ‘I have read and understand the warning above’ and selected ‘Next’.
2. The license agreement was shown and I selected ‘I Agree’ and clicked on ‘Next’.
3. I didn’t change the default installation folder and wanted all users on the computer to be able to use the software. I selected ‘Next’ to continue.
4. To confirm the installation I clicked on ‘Next’.
5. Once the application was successfully installed, I selected ‘Close’.

Conclusion
I’ve been using SyncToy 2.1 for a couple of days and I’ve experienced no problems.

I’ve found the software easy to use and as I type, the software is currently syncing thousands of files between my machine and a NAS. I’m glad I was able to install the old software.
