UAC Elevation

Uncheck if the SC should run without admin elevation

@ThomasLevering: Change added, thanks!

SkyBeam : Where is the ultravnc.ini folder?

When ultravnc.portable exists: <exe folder>\ultravnc.ini
No marker, running as Admin/Service: %ProgramData%\UltraVNC\ultravnc.ini
No marker, non-Admin (user config exists): %LocalAppData%\UltraVNC\ultravnc.ini
No marker, non-Admin (fallback ...

@SkyBeam: .cer was removed as people complained a old certificate was added, I will add it back.

Please replace the .dll files to test:

This is auto updated, based on estimated size of a text string.
Instead of using the EN sizes, they were recalculated based on translated text.

I can't verify each dialog for each language manual.

Please check.

@VersusBG: ResX Resource Manager is designed for .NET .resx files, not native C++ .rc files. So you can’t directly open or translate .rc files with it.
Will not work.

I imported the changes (pos/size) from EN in all other .rc files (automated).

Looks more complicated then initial though, The FileTransfer is GUI based, simulating the UI handling using commandline will take more time.

@VersusBG: Manual merged all except MSI.
Currently, I use a MSI Wrapper around the Inno Setup, so I don't need to maintain MSI and Inno Setup.
The MSI Wrapper also takeover all Inno Setup settings that are mssing in the MSI via a deployment project.

Look in the service manager if uvnc_service is installed. Commands to install the manual service:

Current not, all needed to be redone and it's still work in progress...
Good for telling the check doesn't work...

On hold for a few days, first need to fix some UltraVNC Server Viewer problems.

Perhaps this is the issue: Release summary - May 2026

basso : When you share the same Server with multiple clients they all show the the same desktop.
VNC clones a desktop, it isn't like an RDP Server where all sessions have there own desktop.

brainshell : Thanks 1.8.2.2 will be released in a few weeks, current waiting for other little things that ...

Copy UltraVNC Server (winvnc.exe) to a temporary folder
Run UltraVNC Server as Application
Set a password, and other settings that you want
This create a new .ini file in the ...

Sonderzzz : Running as Service:
Guest user: When he open the systray and click on settings -> nothing happen, it doesn't open
When "Administration password" is configured and [v] user can access is configured -> clicking "Settings" asks "Administration password" to open.

Only when the user is a ...

Sonderzzz : I don't understand your question.

When UltraVNC runs as Service, the .ini file is in %ProgramData% and it can be edited locally by someone with permission to write to that file.
A user can not change that file unless he is administrator. If the user is administrator, he does what he ...

no, it was made that way.

@proger16: Thanks... This was a hard one!

proger16 : Thanks for your tests.
Windows 7: I found, it's the new lib we used to zip/unzip.

Single .EXE now works from Windows 7 (Windows Server 2008 R2) to Windows 11.
