Portable App Development

When using SingleAppInstance=true, is there an alternative to the horrible error message and beep?

Is there any way to get the running instance to come into focus instead, like installed software sometimes does when it only allows one instance?

Cant recompile the launcher with this release, all I get is
a not-so-clear error from NSIS (probably about Language.nsh),
which persists even with simplified *.ini's.

Today I looked into the source folder of Google Chrome Portable, but it seems that there are only the launcher source files. Is the source code if the (online) installer also somewhere available?

Regards,
Leon

here, the location is wrong. It says it goes into Other\Source but it should be App\AppInfo\Launcher\Custom.nsh.

I'm working on a portable version of UMPlayer, but I ran on an issue with the logo licensing:

Hi! I have a game I develop that I want to see portable.
The game itself is already portable, persay. uses only relative paths, and can use it's DLLs from the working directory.
No issue there.

HOWEVER, there is an updater, which is mandatory for continued play of the game.
This updater, written in visual basic, requires a DLL to be registered. It is called Z-Updater, and can be found on sourceforge.

If anyone can edit the source code of the updater to no longer require the DLL, it would be greatly appreciated.

Tell me please, I can not in any way solve the problem ...

Duplicate File Detector at startup creates a folder in the "common documents". I can not simulate the creation of this folder in [DirectoriesMove]...

I was wondering if it is possible to make Nero portable. Sometimes I have files that I need to copy and I am not around my computer, but the computer I am using has a cd/dvd burner. Being able to have Nero on a flash drive would be fantastic. Does anybody have some hints on how I would start this, or if it is possible? Thank you.

Hey there,

I am trying to use the path of a portable application in a registry value. Something like

!define REGKEYS "HKLM\SOFTWARE\Vendor\Subkey\Path=REG_SZ:%PAL:AppDir%\SubfolderofApp\"

apparently won't do anything. Any hints ?

Hi
I´ve been working on a portable app, but i´m stuck on moving a directory from a registry key, that contains double back slash in the string, this is the launcher i've created:

[Launch]
ProgramExecutable=ThumbsPlus\Bin\thumbs8.exe
DirectoryMoveOK=yes

[Activate]
Registry=true

[FileWrite1]
Type=Replace
File=%PAL:DataDir%\settings\ThumbsPlus.reg
Find=="%PAL:LastDrive%%PAL:LastPackagePartialDir%\\
Replace=="%PAL:AppDir%\\

[FileWrite2]
Type=Replace
File=%PAL:DataDir%\ThumbsPlus\Thumbs8.ini
Find==%PAL:LastDrive%%PAL:LastPackagePartialDir%\Data\
