Installer 1.5.2 not working for me in Windows Server 2022

[sergiortc]

I am trying to install Roundcube 1.5.2.
My server is Windows Server 2022 version 21H2 (OS Build 20348.825)
Mi IIS is version 10.0.20348.1
I have installed PHP Version 8.1.6
When I browse to http://localhost/roundcubemail-1.5.2/installer/
I get the following error message:
PHP Warning:  Undefined array key "allowinstaller" in C:\inetpub\wwwroot\roundcubemail-1.5.2\installer\index.php on line 74
Can you help me here?
Thank you in advance.
Looking forward to hearing from you.

Support for PHP 8.1 will be added in the next version of Roundcube, 1.6 (current in release candidate).

[sergiortc]

Thank you, very much.
Could you tell me what is the most recent version supported?

[JohnDoh]

Roundcube 1.2 supports PHP >=5.5 and <=8.0.

Full details of versions and PHP support can be found here https://github.com/roundcube/roundcubemail/wiki/Version-History

Good day.
I hope this will give you information for the initial release.
I am not expecting an answer or help.
This is just FYI.
I downloaded https://github.com/roundcube/roundcubemail/releases/download/1.6-rc/roundcubemail-1.6-rc-complete.tar.gz
Extracted it to wwwroot
so its path is C:\inetpub\wwwroot\roundcubemail-1.6-rc
When I try to browse to http://my domain/roundcubemail-1.6-rc/installer/
I get these error messages:

These warnings can be fixed with composer https://github.com/roundcube/roundcubemail/issues/8573

Good night.
I fixed the ldap3 warnings.
I enabled all the optional extensions, except imagick.
I enabled sqlite database.
I uncommented and set date.timezone.
I set some configuration values and when I clicked on the "Create Config" button I got a 252 lines long list of warnings of the form:

You can ignore these. They will be fixed in 1.6.0 which should be released soon.
