Setting Opera USB as Default browser in Windows Vista

As the title says, anyone know of a way to set OperaUSB (I'm using the latest 9.5 beta) as the default browser within windows Vista?

Any help is kindly appreciated!

Thanks

I pretty much succeeded in my task in playing around with Registry keys.
In future releases, any chance you could include a tool that properly registers/adds Opera portable to the registry?
That would be really useful!

You ignore there 2 problems:

• Benji99 has Vista
• it the Operausb.exe the Standardbrowser is not made. So for a long time the drive assembly letter equal remains and the stick at other computers is not used, is however no problem.

Whats the Problem with Vista ?

Among other things any longer so simply a program than standard program is not to be furnished in Vista. With Opera folds that problem-free only if the English or international Setup were used.

(I only uses Vista a short Time and there was no Problem with Defaultbrowser Opera)

Did Opera@USB use or the english or international setup there?

Hi thanks for the reply!

Unfortunatly with Vista, Windows treats email and Internet browsers differently than other programs.

When you click Default Programs and then "Set Program Access and Computer Defaults", any portable application will not show up in the list because those programs didn't register themselves in the registry.

Furthermore, if you go into "Associate a file type or protocol with a specific program", I can change the file extensions to point to any application because there is an option to browse for the executable.

However, for protocols, and particularly for Opera, the HTTP and HTTPS protocols, there is no browse option, I have to pick a program that is registered in Vista as being able to handle such protocols.

The HTTP and HTTPS protocols seem really important because whenever I click on a URL from another application (be it Skype, MSN, Pidgin, Thunderbird, Outlook, FeedDemon, etc...) those applications will launch the Default browser in the operating system.

Basically, how I fixed the issue was by mucking around the registry in HKLM\Software\Clients\
What I did was install the normal version of Opera and look at the Registry keys and then changed them to point to the Portable version.
It seems the normal installer will add the proper keys there so that Vista can recognize the browser.

i have the same problem, every time i click in a e-mail at a link IE will show up and load the page.
@Benji99: did you uninstall the afterward the normal opera? or do you just have opera + opera-portable installen and just use the portable version?

Right now I have Opera 9.50 installed normally, but I use the Portable version of Opera which is obviously located elsewhere.
I'm a little afraid that if I uninstall the regular version, that the uninstaller will remove the Registry entries that I modified for Opera portable.

The reason is that I don't like to clutter my main hard-drive with installed applications that I don't use.
I like to keep my system as clean as possible.

Actually, this one of the reasons I really like Portable Apps and moving as much as possible toward them.

Miraculix, quick question, which is the best executable for registry entries to point to?

operausb.exe or op.com

I think it's best for them to point to op.com right?

My Opera 10 USB opens all links thanks to this tiny portable open source app.: types1.3.0. My operarting system is Vista. I just changed all portable firefox extensions to opera usb and it works for me. Hope it will help others as well. Good luck.

After firefox screwed up my associations I wanted to do the same but as I didn't remember nor couldn't google quickly the proper solution, I did a quick workaround like this: backed up (moved) opera usb folder, did normal non-usb installation with "set as default browser" option into the desired path and then replaced it with the backed up one
(I keep the folder on HDD, treat is as local so not sure if on usb will work)

if someone knows the exact registry keys for this, please share!

I posted here an solution (but in german).

Try to figure it out, it's with screen shots and use google translator.
