yes there was previous version I went to C:\texlive and deleted the
folder C:\texlive because last time also I had similar problems
and could not install last time also successfully. I tried 2-3 months back
this same procedure but failing to proceed. I used overleaf online
to write my reports. This time I thought of doing again from where last
time I could not proceed.So I had deleted the folders assuming that ,
that was required to do.

I downloaded 2 files on from
http://ctan.math.utah.edu/ctan/tex-archive/systems/texlive/tlnet/
link one is install-tl-windows.exe and another was
install-tl-windows.exe.sha512 now I did go inside the downloaded
folder C:\Users\Debian\softwares\latex>certutil.exe
-hashfile install-tl-windows.exe.sha512 SHA512 SHA512 hash of
install-tl-windows.exe.sha512:
a633ea2bed732f42f942e532a2935805e93405834a710cbe3b81149f9e740a55b63b621a95cb1bbb32a399ab1138889c7c0a90435e602c85089190a46017d632
CertUtil: -hashfile command completed successfully.
I think this checked the hash of install-tl-windows.exe.sha512 but I think
I should have checked the hash of
the file install-tl-windows.exe on the download link got downloaded with
name (I did not changed anything)
install-tl-windows_2.exe so I did now
C:\Users\Debian\softwares\latex>certutil.exe
-hashfile install-tl-windows_2.exe SHA512 SHA512 hash of
install-tl-windows_2.exe:
ab9298b865472fbd0d7630849a624cf4a09ba625371c6845937400bd94b7fd05a10bebdf5295d5e6cb4242fd1b4bdc76e52a3cca72a4440e3ff7bb068f9b68fa
CertUtil: -hashfile command completed successfully.

So these are the checked value of hashes what does this mean.I tried  not
using the network downloader, and instead install it from the ISO:
so followed this link
  https://tug.org/texlive/acquire-iso.html and tried downloading this one

http://mirror.iopb.res.in/tex-archive/systems/texlive/Images/texlive2019-20190410.iso

the file could not be successfully mounted.I then tried extracting the
texlive2019-20190410.iso via 7zip 90% extracted but then some where later
files could not be extracted.

so I have a corrupt ISO which I am trying to download again from some other
mirror. I don't understand the above checksum outputs because I fear if  I
start installing again I will land in same situation.
