As was mentioned, you can change the schema to allow longer strings.
However, another approach is to just break out common expressions from
your conditions into your own properties. So instead of repeating
the expression '(VersionNT = 501) AND (WindowsBuild = 2600)' to check
for WindowsXP, you can use a type 51 action (set property) to create
your own property called WindowsXP:
<CustomAction Id="SetWindowsXP" Property="WindowsXP" Value="1">
<InstallExecuteSequence>
<Custom Action="SetWindowsXP">
(VersionNT = 501) AND (WindowsBuild = 2600)
</Custom>
</InstallExecuteSequence>
You would sequence this before any of your conditions that use this
property, naturally.
You can think of this as a "refactoring" for MSI conditions: replace
complex conditions with a named property that reveals your intent in
using the conditional expression.
