NI VISA cannot install

I have a problem with installing  NI VISA.  It was installed my computer but when I run my python script it was giving me an error.

I googled the root cause of error and in couple forums It was saying uninstalling and installing NI VISA can help or to solve the issue.

NI VISA is removed and installed coupled times. I also removed some files that is started with NI_VISA. 

RIght now,  when I tried to install the visa I am seing the below message. Also, I cannot see the National Insturements Folder in the Start Menu.

Can someone help me to figure out the installing issue?

The error message basically says that you already have a VISA version on your machine which is never that the one you are trying to install.


Probably, there are some leftovers in the registry. So either clean the registry, or try to install an appropriate version.
