#36 WinNMP 20.05 MariaDB Install issue

[Al]

Hi,

I was walking through the use of your excellent WinNMP with a group of 5 computing students, explaining where to go to download, and demonstrating use. Then a student said he could not install the current version correctly with mariadb error messages. After the tutorial I backed up my WinNMP folder, uninstalled and installed the latest WinNMP in order to try and recreate the students issue; which I did.

Installation is fine, however when the program runs, the following error dialog pops up:
mysqld.exe - System Error
The code execution cannot proceed because server.dll was not found. Reinstalling the program may fix this problem.

After clicking OK, a second dialog is displayed:
[Window Title] Unable to start all servers!
[Main Instruction] Error running mysql_install_db
[Content] FATAL ERROR: database creation failed

I followed the link for windows errors, and installed the recommended fix https://aka.ms/vs/16/release/vc_redist.x64.exe

did a reboot, tried starting WinNMP again, same errors happened.
c:\WinNMP\bin\mysql.bat doesnt exist to delete it.

Tried the following from an admin command prompt:
C:\WinNMP\bin\MariaDB\bin>mysql_install_db -d c:\WinNMP\data
Running bootstrap
ERROR: Can't write to mysqld's stdin
FATAL ERROR: database creation failed

I'm at a loss as to whats wrong. I've spent the evening trying to work out what and where server.dll is without luck.

I'm using up-to-date windows 10
Microsoft Windows [Version 10.0.18363.1139]

WinNMP MAnager shows MairaDB as 'Not installed'.

Can someone please help?

Thanks in advance

Thank you for the report.
There was a bug in our build script and somehow binaries for the wrong MariaDB versions were included.
We have uploaded the correct installer and components now.
Please re-install WinNMP and let us know if you still have issues

Ok, I solved the issue and this solution may works for other too.
Head over to https://downloads.mariadb.org/mariadb/10.4.15/#os_group=windows and download the mariadb-10.4.15-winx64.zip. Unzip it, go inside the bin folder and copy all the files from there, then move to your winnmp directory, and the go to bin\MariaDB\bin directory. Now copy and replace all of them. That's all!
Restart the winnmp and it will start working.

the issue is now fixed. please re-install
