Hi Bruce,
I did this the following (hopefully correct) way:
<InstallUISequence>
<Custom Action="GetMyEnvVar" Before="LaunchConditions"/>
</InstallUISequence>
<CustomAction Id="SetSystemMaxRam" Property="MY_ENV_PROPERTY"
Value="[%MY_ENV_VAR]" />
You can use [MY_ENV_PROPERTY] to write the correct registry string.
regards,
Markus
