Me too, and I am still trying, maybe it is a problem with updates, they did on the installer,
I hope that we get an answer soon.
I can install it with not a problem.
And one user on Russian forum installed MT5 again - no problem (he told that not a problem).
------------------
It may be the problem in case you have old Windows version (Windows 7 for example), or Windows with 32-bit.
But not any problem at all in case of Windows 10 64-bit.

I am actually using windows 11,
and I tried to install it from MetaTrader 5 Trading Platform for Forex, Stocks, Futures,
and also from a broker,
and it did the same thing,
I tried also to install it on a windows10 pc,
and the same thing happened!

Ill I get is the warning
As I told - some users do not have this issue.
About warning - no one knows about this warning ... because two users here (incl you) on this thread reporting about warning, and none of them published anything about warning, no any screenshot, no any Windows versions by screenshots... nothing ... just talking.
----------------------
I want to repeat - some users do not have this issue (and those users did not provide their technical details too).

then I uninstalled it,
and when I try to reinstall it, the installer file does not work properly,
it shows the warning, and when I click yes, it does not do anything,
any help regarding this issue will be appreciated
