Adobe Flash Builder 4 Installation Error: Exit Code 7

Flash Builder , Flex , IDEs , Misc Add comments

I decided to promote my Flex IDE installation from Flex Builder 3 and Gumbo to latest release "Flash Builder 4".

I downloaded the application installer from:

When I ran the installation, logged on as an Administrative user on my Windows XP desktop PC,  the installer would run, but crash-out mid installation with the following Error:


Exit Code: 7

————————————– Summary ————————————–

- 0 fatal error(s), 3 error(s), 0 warning(s)
 ERROR: Custom Action for payload {177E1CA1-14CC-4398-AB15-A5746EFE8F22} Adobe Flash Builder returned error. Failing this payload.
 ERROR: The following payload errors were found during install:
 ERROR:  – Adobe Flash Builder: Install failed



Turned out that my user account on Windows was the problem.

There is an apostrophe in my surname "O'Doherty" which was throwing the installer off.

I simply logged into another (backup) account that I have on the same PC called "Admin" and the installion executed WITHOUT ERROR!


Also would like to credit Joe Billman who also has details of this on his blog.  Although his issue was with the ampersand character "&" it still was due to the characters in his Windows Account Name.


One other thing I haven't gotten around and that I thought I would mention is, being a registered owner of Flex Builder 3, I obtained a serial number from the Adobe site for Flash Builder 4 (I think it simply extends the trial), but the installer didn't accept it as a valid key?

    Hi Ahmad,
    I would suggest that you review the installation log file to see if there's anything there to indicate why the installer is failing.

    Hi Ganesh,
    I believe you can install both on the same machine using the "stand alone" option, but I would set a restore point and backup before installing so you can roll back your system if there are any problems.

    I run in to a very similar issue. ERROR 26656 Unable to create directory \\<Server>\<user profile directory>\..\Adobe Flash Builder Burrito Preview

    My assumption is that this fails because my user profile is not on my machine and the path is trying to move up a directory from my user name where I do not have permissions. Does anyone know how to change this?
