Portable App Development

Suppose I want to make a program portable, which is a Freeware but not Open Source. Normally I need in this case a permission of the developer of the program. However, I've read here several times in the forum, that it would be with an online installer possible to make a program portable without the consent of the developer. Personally I consider this possibility for something bizarre, because I am of the opinion, that the main feature of an online installer is to make the size of the installer file (*. paf.exe) smaller. Is my assumption so far correct?

GSView Portable has been created.

Its a net-installer since this is shareware?

Code is here

I've read through several times the complete documentation of Languages​​. Based on the explanations in the "Setting a custom language environment variable" I've come to the conclusion, that the environment variable %PAL:LanguageCustom% exclusively will be applied in the PortableApps.com Platform. This environment variable is generated by the sections [Language] and [LanguageStrings].

Well, the subject says it all. Task Coach portable paf setup even does not take the time to ask the user if he wants to keep his .tsk. So, updating Task Coach paf instead of installing to a new folder to keep the old tasks and settings safe cannot be recommended, unlike other paf's.

Edit 29 Jan: Good chance that I didn't find a bug but that the problem is me being confused with installation locations, .lnk's and backup copies. I am sorry. I need a secretary ...

I believe i have found a glitch ..
no matter what i do ..
PAL is unable to portabilize:
HKCU\Software\Classes\CLSID

Here is my launcher configuration:

Thank You,
PS: i have tried [RegistryCleanupForce] and it sill wont clean.

EDIT
I just tested on a x32bit machine and the CLSID is portabilized?
This is only a problem on x64bit machines.
* I also removed the 64bit version to test, and same problem occurs on a x64bit machine.

UPDATE

I use the PortableApps.com Application Template 2.2 to create the basic directory layout. Among other things I add for example one folder named "Test" with various files in the folder Data. Then I create the launcher and installer.

If a now install the portable app with the nstaller, I detect that the folder Data contains no folder "Test". Why is that so?

Assuming we have a configuration file as follows:

[username1]
.
.
Path=X:\folder1\folder2\folder3
.
.

Here is "username1" the name of the logged user on the host PC. If I now insert the USB flash drive on another PC, where "username2" is the name of the logged user, then the above configuration file are changes as follows:

[username1]
.
.
Path=X:\folder1\folder2\folder3
.
.
[username2]
.
.
Path=Y:\folder4\folder5\folder6
.
.

I´ve tried to realize the automatic language switching in my portable app Tomahawk PDF+ Portable. To that extent I've created a folder named "Languages" with all language files inside of the folder DafaultData\settings. I also have created a file "custom.nsh" with the following code:

${SegmentFile}

${SegmentPrePrimary}
	ReadEnvStr $0 PAL:LanguageCustom
			CopyFiles /SILENT $EXEDIR\Data\Languages\TPdfPlus$0.lng $EXEDIR\App\TomahawkPDF+
			Delete $EXEDIR\App\TomahawkPDF+\TPdfPlus.lng
			Rename $EXEDIR\App\TomahawkPDF+\TPdfPlus$0.lng $EXEDIR\App\TomahawkPDF+\TPdfPlus.lng			

Assuming the installer AppnamePortable_x.xx.x.paf.exe will installed the appropriate app at X:\PortableApps\AppnamePortable. Are the following 2 statements correct?:

$INSTDIR=X:\PortableApps\AppnamePortable

$EXEDIR=X:\PortableApps\AppnamePortable

If a local registry key or file has special permissions required by a local version of the portable app, currently we lose them.

Example:

When you install Steam, at install time it sets HKLM\SOFTWARE\Valve to have full access by the Users group, so even limited users can write to it.
