I'm getting a problem when I try and start Firefox. I get the message:

"Firefox LiberKey Portable Edition
Unable to prepare the execution context for the portable application.
Please close all open windows and start again the portable application."

If I remove the Data folder, I get a window which says "Firefox is already running, but is not responding". Firefox isn't running, I've checked using Task Manager.

I've tried deleting FirefoxLKL.dat, but then I get the message "Portable application information file is missing!"

Any ideas? Many thanks.

I've found the cause of the problem.

There is a directory called "LiberKey\Apps\Firefox\Data\settings\Crash Reports". It contains a single file "InstallTime20091102152451" 10 bytes long, which only contains the text "1258571611".

If I delete the file (so that the directory "Crash Reports" is empty) Firefox still crashes.
If I rename the directory Firefox starts happily.
If I delete the directory Firefox starts happily.

Most peculiar...

I have the same problem with chrome portable, but I don't know how to solve!
Same problem both on 7 64bit and vista 32bit.

please follow the following procedure:
- Backup the folder Liberkey\Apps\Chrome\Data outside the Chrome folder
- Remove the Chrome application
- Install it again

Let us know if Chrome is working successfully or not.

I have double checked, now it's starting fine on 7 64bit, where I don't have any browser installed.
On Vista, where I have google chrome 5 installed, I get this error even after deleting and reinstalling LiberKey Chrome.
