Error Message #0

"Error #0" is a message produced by the underlying Adobe AIR software, rather than Market Samurai itself. By itself it doesn't tell us exactly what's wrong. There are a number of potential causes, so we'll step you through the various fixes in order of their likelihood.

#1: Your user account has restricted access on your computer.
The most common cause is that you are using a restricted access account on your computer - and the restrictions on your account are affecting the installation of Market Samurai.

You can find detailed instructions on checking and adjusting this here:

After this, try installing Market Samurai again.

#2: The User Account Control (UAC) may be turned off 
(this will affect only users with Windows Vista, Windows 7 or Windows 8)

This can be checked by going to "Start" > "Control Panel" > "User Accounts". From there, open UAC and make sure it's enabled. (On Windows Vista it's a simple checkbox; on Windows 7 and Windows 8, the slider should be set anywhere except the bottom-most setting)

More detailed instructions are available -
Windows Vista:
Windows 7/Windows 8:

Then retry the installation.

#3: Corrupt Installation File
If those measures don't work, then you probably have a corrupt download file. To resolve this issue, please follow these steps:

Go to to run "Microsoft Fix-It", which is designed to clean up problems which can get in the way of uninstalling and reinstalling software.

As an alternative, download and install "Revo Uninstaller" which is available on a free 30-day trial from - use this on it's highest setting to completely uninstall Market Samurai and Adobe AIR, traces of which which may be hanging around and blocking a proper reinstall.

Perform a search on your hard drive for all files that end in ".air" - delete these, as your computer may be caching the corrupt file, preventing you from downloading a new copy of the file (here's an illustration of how to find the Search feature on all versions of Windows)

Be sure to check that there are no AIR (files with the extension .air) in C:\Program Files\Common Files\ - delete any you find. And clear out any temp files that you can in C:\Users\[your username]\AppData\Local\Temp - it's likely some won't let you delete them, but get rid of as much as possible.

Download the Market Samurai AIR file again from your personalised download page - use the link under option 2, Manual install - and try reinstalling again.


If none of those steps fix the problem, you'll need to locate the AIR installation log (here are instructions for Windows and MAC), and then attach the install log when you submit a support ticket.
