First, I'm not intimately familiar with what you're doing, but have you tried
making use of the standard IIS custom actions to do what you want to do? See
wix.chm for the list of elements in the IIS extension - one of them may be able
to help you do this, and then you'll get install, uninstall, rollback, etc. all
well-tested, and for free.
If it isn't, could you file a feature request or bug outlining the scenario you
wish IIS Extension supported? This sort of functionality will be better tested
and more reliable if WiX supports it natively, so you don't have to do things
like this yourself.
Anyway, to answer your original question, try escaping them like this:
"[\[]" (without quotes) for the open square bracket.
"[\]]" (without quotes) for the ending square bracket.
I believe this is the standard MSI way to escape these characters.
Thanks,
Mike Carlson

Subject: [WiX-users] Square Brackets in a Custom Action
I have a custom action that executes appcmd (the IIS 7 tool for metabase
modifications) and it needs to contain '[' and ']' in the command line.
The following custom action fails to compile with the square brackets:
<CustomAction Id="SetDefaultAppPoolTo32Bit"
Directory="TARGETDIR"
ExeCommand="[WindowsFolder]\system32\inetsrv\appcmd.exe set
config -section:system.applicationHost/applicationPools
/[name='DefaultAppPool'].enable32BitAppOnWin64:"True"
; /commit:apphost"
Return="ignore"
Execute="commit"
HideTarget="no"
Impersonate="no" />
If I remove the square brackets it executes but performs the wrong
function.
I tried XML escaping them as follows:
<CustomAction Id="SetDefaultAppPoolTo32Bit"
Directory="TARGETDIR"
ExeCommand="[WindowsFolder]\system32\inetsrv\appcmd.exe set
config -section:system.applicationHost/applicationPools
/[name='DefaultAppPool'].enable32BitAppOnWin64:"
;True" /commit:apphost"
Return="ignore"
Execute="commit"
HideTarget="no"
Impersonate="no" />
Any other ideas? (besides shipping a separate .bat file that performs
the function).
Thanks.
