WampServer

I just installed the MariaDB 11.6.2 Add-On to the latest WampServer to update my installation from mysql 8.2. I have already successfully upgraded the base install, added Apache 2.4.63 and php 8.3 and 8.4.

Before the installation program finishes, it throws a System Error saying

"The program can't start because icuuc.dll is missing from your computer. Try reinstalling the program to fix this problem."

Which installer?

> because icuuc.dll is missing
icuuc.dll is a Windows system file and is not installed by Wampserver or addons.

- Go to VisualCppRedist AIO All Releases
Download the latest version of VisualCppRedist_AIO_x86_x64.exe and run it as administrator. All necessary redistributable VC++ files will be installed and any excess or obsolete files will be removed. To ensure that everything runs smoothly, you'll need to disable certain applications when prompted to do so by the VC++ Redist installer.

Hi,

I have already installed the latest VCredist_2022 - 14.42.34433 - both x86 and x64 before I begun updating my add-ons.


I have installed all the following MariaDB add-ons sequentially to test where the issue might have begun.

10.11.10 - no issues
11.0.6 - no issues
11.1.6 - no issues
11.2.6 - no issues
11.3.2 - no issues
11.4.4 - System Error - mysqld.exe - error as quoted in original post
11.5.2 - System Error - mysqld.exe - error as quoted in original post
11.6.1 - System Error - mysqld.exe - error as quoted in original post

This WampServer installation is on Windows Server 2016 - with the latest security patches installed

This is where I downloaded the latest VCredist_2022 packages from

[learn.microsoft.com]

It states the latest supported versions :-

The latest version is 14.42.34433.0

After installing all of these versions, I can use the TrayManager to switch between these versions

10.11.10 - no issues
11.0.6 - no issues
11.1.6 - no issues
11.2.6 - no issues
11.3.2 - no issues

but as soon as I try to switch to any of these versions

11.4.4 - Tray icon stays ORANGE - mariadb does not start
11.5.2 - Tray icon stays ORANGE - mariadb does not start
11.6.1 - Tray icon stays ORANGE - mariadb does not start

> because icuuc.dll is missing from your computer.

I repeat that icuuc.dll is a system file and is not installed by Wampserver.

- Are you up to date with Windows updates?

Open a command window as administrator (right-click on the Start icon, then Terminal (Administrator) and, in the terminal, type :

sfc /scannow

This will check the system files and repair them if necessary, but I don't know if it will add the missing file.

I found this

[mariadb.com]

It seems to be a mariadb issue

Hi,

There's nothing I can do. You're doomed to stay with MariaDB 11.3.2.

The installers for MariaDB versions 11.4.4 and higher have MinVersion=10, which includes Windwos Server 2016.
I'll have to use MinVersion=10.0.15063, i.e. from Windows 10 1703, which excludes Windows Server 2016.

Sorry!

No worries. We need to move that server off Windows 2016 in the near future anyway.

Should I assume we are better staying on the 10.n.n series rather than getting stuck on 11.3.2 and missing any security fixes in the 11 series

I don't need any new features so I think it would be better to stay on a still supported client (unless of course they break the 10.n.n installer too)

Your thoughts?

Thanks for a great project by the way. It makes it very easy to keep up to date with versions/updates

Hi,

From what I've read at MariaDB, 10.10 is "long term support" and 11.3.n is not rated "Short Term Support", unlike 11.1.n and 11.2.n.

One final comment.

It would be really useful if you could add " LTS" after the appropriate MariaDB/mysql versions on the download page. [wampserver.aviatechno.net]


For example -

MariaDB 10.10.6 64 bit x64 MD5
MariaDB 10.11.10 64 bit x64 LTS MD5
MariaDB 11.0.6 64 bit x64 MD5

According to [mariadb.com] - 10.6, 10.11 and 11.4 are the currently supported LTS versions

This has just been done

Cool! Thank you.
