I have been trying to download some ISO from Win ISO Downloader, but I am getting this error
Please see this link for the actual error.   Win ISO Downloader Error Image [Screenshot]
I have tried on different machines, it works fine with no issues, but after some time, it starts showing problems after a while and never allows me to download any other ISO.
 
Any help will be helpful.
 
I am using 
Windows 10 x64 (ver. 20H2)
 

Hello! Good day!
I'm new here in this community. So, I just want to ask what to choose in Windows ISO Downloader?
I want to download Windows 10 64-BIT, But, it shows 2-tabs of Windows 10.
I don't know what to choose. Are they same but different links?
Here is their links:
1st Tab of Window 10: https://software-download.microsoft.com/sg/Win10_20H2_v2_English_x64.iso?t=34b24718-7aa3-470e-81a2-975f32fb27af&e=1609057741&h=4499579fb491c123ec749d3149b40e12
2nd Tab of Windows 10: https://software-download.microsoft.com/sg/Win10_20H2_v2_English_x64.iso?t=2272e9ff-3228-4ac2-a6bc-772e550f7178&e=1609058027&h=6d70362e8b5bb1ecabe972d2e7dd76ac

Thank you.

Dear Wincert Team
pls add a Vista download link!

So this is the problem. I download and run the Windows ISO Downloader , version is up to date (6.02) . Whenever I pick any other windows option besides windows 7 , the tool greys out and crashes. 

I have went through the FAQ's and I do not have the lines in the HOSTS file that should be removed, I disabled adblock when downloading, I have turned off firewall , I do not have an antivirus program installed. TLS 1.2 is enabled. I started the tool as administrator and have IE 11 and .NET framework 4.7.1 installed
