Ran this Tool check_vcredist.exe

Installed all Packages as per the Tool
Ran Tool again
It said All Packages needed for WAMP are there

I'm on a WIN8.1 64bit (Acer V5-561G) laptop

Installed wampserver3.2.3_x64.exe
At the end of the installation i get the error:
-------------------------------------
httpd.exe - System Error
<<The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer>>
-------------------------------------


Did many many things as per various suggestions

+ updated Windows
+ uninstalled MsVC++ 2015-2019 Redistributable (x86) - 14.28.29913
+ uninstalled MsVC++ 2015-2019 Redistributable (x64) - 14.28.29913
+ reinstalled both
+ ran WAMP (stayed on Amber) 2/3 services running

+ uninstalled MsVC++ 2015-2019 Redistributable (x86) - 14.28.29913
+ uninstalled MsVC++ 2015-2019 Redistributable (x64) - 14.28.29913
+ installed MsVC++ 2015 Redistributable (x86)
+ installed MsVC++ 2015 Redistributable (x64)
+ uninstalled WAMP; and reinstalled it
+ ran WAMP (stayed on Amber) 2/3 services running

+ uninstalled MsVC++ 2015 Redistributable (x86)
+ uninstalled MsVC++ 2015 Redistributable (x64)
+ installed MsVC++ 2017 Redistributable (x86)
+ installed MsVC++ 2017 Redistributable (x64)
+ uninstalled WAMP; and reinstalled it
+ ran WAMP (stayed on Amber) 2/3 services running

Each time i reinstalled WAMP, i kept getting the "MISSING api-ms-win-crt-runtime-l1-1-0.dll" ERROR, and if i ran WAMP, only 2 out of 3 services would show as running (Amber icon in system tray)

Hope someone can guide/help

Thank you very much for your guidance.

On the 29th, Windows Updates wouldn't work well (seemed to be getting stuck for ever). So i had downloaded the 8 .msu files from microsoft but when i went about installing (acc. to the order stated), i would get the msg "Not applicable for your computer". Then i found this forum and went through your Troubleshooting post. Infact, i had even downloaded [update-for-universal-c-runtime-in-windows] (KB2999226); but the same result when i tried to install it. After everything failed, Windows Updates began working and it was hours of updating after that. After each restart, i would try the sequence of uninstalling/re-installing the Ms VC++ 2015-2019 x86 n x64 Redistributables; and then the same with WAMP.

An hour ago today (31Mar, 1am here IST), after i saw your reply, i tried installing (KB2999226), and it got done like jelly smiling smiley Was so good to see that happen. I tried running WAMP; but it didnt go to Green.

I thought i'll try the earlier 8 MSU files again; but again none of them were 'applicable'.
There was one other file (besides the 8 MSU) --- windows8.1-KB4540725-x64.msu --- this one installed successfully.

On the other side, Windows Update was showing about 1700 MB worth new updates

Just before i went to do that, i thought to do the routine once more

+ Uninstalled MsVC++ 2015-2019 x64 14.28.29913
+ Uninstalled MsVC++ 2015-2019 x86 14.28.29913
+ restarted WIN
+ installed MsVC++ 2015-2019 x64 14.28.29913
+ installed MsVC++ 2015-2019 x86 14.28.29913
+ restarted WIN
+ installed WAMP
+ restarted WIN
+ ran WAMP

********** and it went GREEN! ***********

was all Hallelujahs!!! relieved & glad. Many thanks to u; God bless~
