Note that defining UMUI_SERIALNUMBERPAGE_TEXT_TOP doesn't change the Serial Number instruction text.

Thanks!

Seems some colors are defined in UMUI and can't be defined in an own theme/skin.

The parts I have problems with have I marked red in the screenshots...

My theme is based on the "Gray" theme...

UMUI_UNPAGE_SERIALNUMBER doesn't appear to work. Could I be doing something wrong?

Call must not be used with functions starting with "un." in the non-uninstall sections.
Usage: Call function_name | [:label_name]

Hello,

I use NSIS 3.04 with UltraModernUI 2.0b5 and I encountered this bug:

When I try to install software to unicode path (czech characters) like this: D:\přílišžluťoučkýkůň\Modern UI Test
it gets converted into this:
D:\prílišžlutouckýkun\Modern UI Test

NSIS with MUI2 works correctly, so I presume it is bug in UMUI:

I used oficial example from NSIS documentation: https://nsis.sourceforge.io/Examples/Modern%20UI/MultiLanguage.nsi
Tested on Windows 10.

Hello,
I have a problem with the UAC plugin and UMUI not setting the language in registry.
When I select a non-default language from the list, UMUI creates a new instance with the /L parameter. When I elevate at a later step, this parameter is passed to the inner instance and the language is correctly written to the registry.
When I leave the default language from the list, the language page is not displayed in the inner instance and the UMUI_MULTILANG_GET macro goes to label checkRegistery: and since there is no value in the registry, it goes to endlang, skipping the UMUI_ADDPARAMTOSAVETOREGISTRYKEY call.
I think the UMUI_MULTILANG_GET macro should always call the UMUI_ADDPARAMTOSAVETOREGISTRYKEY macro in order to always write the selected language to the registry, even if it's the default one.

Regards,
Alex

I will request an option to use own code for the repair feature.

Or: Improve the existing repair feature.

I wrote two versions of an installer for BleachBit.
One with MUI2, the other with UMUI.
I would like use the UMUI version, but my code for the repair feature in the MUI2 version seems to be better then what UMUI brings with it.
Great would be, if I can have the best from both versions... This is the reason for my request.

You can find the MUI2 version to have a look at my repair feature code here:
https://github.com/bleachbit/bleachbit/blob/5707557f4ae0072f0fb267f6db7f0cdf6c95834e/windows/bleachbit.nsi

In the German Translation, the info text to the license have three lines where the last line is cut.
Can you fix that in the next release?

On my components page, the info that the user wants to interact with (the components) is squished by a whole bunch of wasted space:

How do I turn off the left image for a page?

Alternatively, how do I fix the layout so the components use the space better?

(I started with this example from NsisMultiUser. )

When there is a custom page installed and the user press the 'Cancel' button before this page is arrived, then 'Cancel' jump to the custom page instead to UMUI_PAGE_ABORT.

Sample code:
!insertmacro UMUI_PAGE_MULTILANGUAGE
!insertmacro MUI_PAGE_WELCOME
!define MUI_LICENSEPAGE_RADIOBUTTONS
!insertmacro MUI_PAGE_LICENSE "$(MUI_LICENSE)"
!insertmacro MULTIUSER_PAGE_INSTALLMODE
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro UMUI_PAGE_SETUPTYPE
!insertmacro MUI_PAGE_COMPONENTS
!insertmacro MUI_PAGE_INSTFILES
!define MUI_FINISHPAGE_NOAUTOCLOSE
!define MUI_FINISHPAGE_RUN "$INSTDIR\${prodname}.exe"
!define MUI_FINISHPAGE_LINK_LOCATION "${PRODURL}"
!define MUI_FINISHPAGE_NOREBOOTSUPPORT
!insertmacro MUI_PAGE_FINISH
!insertmacro UMUI_PAGE_ABORT

I am trying to install UltraModernUI in a CI/CD pipeline using /S option. However, I can't seem to find any way to get a 'Complete' install (I assume I am getting the 'Default' install since I am missing some stuff...)

Would it be possible to add a flag to have the 'Complete' install (or make a 'Complete' install the default when '/S' is passed).

IMHO you should use a translation system based on volunteers for translation of UMUI.
I can suggest you https://translations.launchpad.net.
