Portable App Development

I've been working on a launcher for a program called stickies. Yes I know it's not open source, but I use it a lot and it's legal so I'm just making a launcher for myself. Anyways I was wondering how you check the system to see if a program is installed. In the cleanup section of my program I have it move files from the App data folder if they're accidentally put there, then delete them. Well if stickies is installed I don't want to do that I just want to make new ones. Can anybody help me? And if you want I can email you the launcher.

I've put up a new page on Ryan's PortableApps wiki explaining how to check if your appicon.ico complies with PortableApps developer standards.

If there's an artist or dev out there that can figure out how to use @icon sushi to create new icons or add more sizes & bit depths to and existing icon that would be great.

Because I have nothing better to do here at 3 in the morning, I thought I'd go through and find which URL's displayed in the PortableApps.com Splash screens actually didn't exists, here's the applications who need to have aliases added to there actual page.

I would like to create a kind of generic installer / downloaded for applications that are maybe to large to be put inside the installer by Downloading the installer or zip file by the installer.

- User starts the installer
- Autodetect and select PortableApps folder
- Deploy the PortableApps template launcher and folder structure
- Download the main application (optionally choice of download locations) to temp
- After download unzip or install deploy the app in the correct portable location

I just have some ideas to improve the operating systems page under applications.

First off, I found some nice Tango style icons for Mac and Linux that seem to be GNU GPL licensed, I think they would look fantastic there. There's a bit of choice for Mac, and Tux is beside the Lego man, here.

Also, I think we should add a better screenshot to the Mac On a Stick Page (I can do that), and maybe ask the owner of the tutorial if we can post it here, and even post the document that gman(?) posted in the Other Apps Support forum.
