I am wondering whether or not LPCExpresso and LPCOpen and workspaces can all be installed on a thumb driver.
the goal is to have a complete portable development environment.
So the real question is how much junk does Eclipse and other packages place in the registry?

LPCXpresso does not use the Registry directly (although the installer does place some install/uninstall information there, it is not used by the product when running).

We have not tried it, but I don't see any reason why it should not work, subject to the following caveats:
- If you want to debug, drivers for USB debug adapters will need to be installed on each machine. They can be found in the Drivers directory of the install directory
- Any target machine will need the Visual Studio redistributables installed. Many machines have these installed, but if not, you need to run the vcredist_x86.exe installer found in the install directory
- Performance is likely to be slow. The IDE uses its install directory to cache a lot of (run time) information. USB flash drives are typically very slow for this sort of information
- There is some configuration information stored in the "configuration" (!) directory. Some of this includes path information, including the drive letter. I don't expect this to cause any significant problems
- Workspaces are not designed to be portable like this. They will contain full paths that are likely to cause issues when moving between machines of the USB flash drive has a different drive letter (i.e E: or F:). However, you can normally recover this by using File->Import, General/Existing projects into workspace

There may be others, but these are the ones that I can think of immediately. All I can suggest is - try it and report back your findings. Good luck.

When it was Code Red, they said that it did not use any registry.

However, the licence file(s?) goes in "Documents and Settings"/"User" <yourname>/something
And debugging etc. runs scripts that need a windows "cscript?" somewhere on the path.
Also USB device drivers are installed (on the PC) at installation.

So probably not.

Also, Java bloatware is huge so you would need a big memory stick.
My 7.4 installation on Win7-64 is 741 megabytes. That's without the workspaces.

thanks, I'll try it and see.
slow does not matter as much as the convenience of take-it-anywhere.
And I really just want to write and compile code. I can debug on my main dev PC.
I can sync up source code from a solution folder to my main development PC when I make changes.
