Problem updating to PHP 7.4 etc (1 reply)

I had Wampserver 5.2.6 with Apache 2.4.37, PHP 7.3.1, MySQL 5.7.24

I want to upgrade to PHP 7.4 and then 8.0, and have tried following the instructions in [stackoverflow.com], and downloading from [wampserver.aviatechno.net].

I have therefore run the following .exe (with several reboots):
vcredist_2022_x64, vcredist_2022_x86, wampserver3_x86_x64_update3.2.7, wampserver3_x64_addon_php7.4.27, wampserver3_x64_addon_php8.0.14

and a few others in case they are of interest later:
wampserver3_x64_addon_php8.1.1, wamp3_x86_x64_aetray3.2.4.2, wampserver3_phpsysinfo3.4.0, wampserver3_x64_addon_apache2.4.52, wampserver3_x64_addon_mysql8.0.27

After all this and another reboot, my wampserver starts OK, but it looks to me as though the versions available to me are only what I had before (eg PHP 5.6.40 to 7.3.1, Apache 2.4.37).

Looking a little closer it all seems OK as I see the folders for php 7.3.1 etc in wamp64/bin OK, and localhost says that Wampserver is at Version 3.2.7 - 64bit.

The one oddity is that when I run check_vcredist.exe it says that both Visual C++ 2015-2022 x86 - 14.30.30704 and Visual C++ 2015-2022 x64 - 14.30.30704 are **** NOT INSTALLED ****. The actual versions of vcredist_2022_x64 and vcredist_2022_x86 I have downloaded and installed are 30708, as is confirmed when I try to reinstall them. I have tried downloading again but get the same results.

Have I missed something to get the latest versions of PHP and Apache available to me?
