What does a verbose log say?
Also, what you have written will ALWAYS set the property to the local
computer's name during the execute sequence no matter what was in the
registry.
Do you want something more like this?
<SetProperty Before='InstallInitialize' Sequence='execute' Id='SQLSERVER'
Value='[ComputerName]'>NOT SQLSERVER</SetProperty>
<Property Id='SQLSERVER' Secure='yes'>
<RegistrySearch Id='RepositoryLocation'
Key='SOFTWARE\MyCompany\MyProduct\MyVersion\MyComponent'
Name='RepositoryServer'
Root='HKLM'
Type='raw'
/>
</Property>
Replace "execute" with "both" if you display/use SQLSERVER in your UI
sequence.

Subject: Re: [WiX-users] Referencing other property as default value of a
property?
Hello,
Does anyone know the solution to this? I have a similar problem with setting
the property through a CustomAction. I understand Sunghwa was getting the
"action" error because "Id" was not defined. I no longer get the error but
the property is not being populated. This is what I have
<CustomAction Id="SetSQLServer" Property="SQLSERVER"
Value="[ComputerName]"/>
<Property Id='SQLSERVER'>
<RegistrySearch Id='RepositoryLocation'
Key='SOFTWARE\MyCompany\MyProduct\MyVersion\MyComponent'
Name='RepositoryServer'
Root='HKLM'
Type='raw'
/>
</Property>
<InstallExecuteSequence>
<Custom Action='SetSQLServer' Before='InstallInitialize' />
</InstallExecuteSequence>
SQLSERVER is always empty. I would like SQLSERVER to default to the
ComputerName if the reg key doesn't exist. It seems like the SetSQLServer
action is not being called but I am not sure. Any ideas on how to fix this
or debug it would be appreciated.

Subject: Referencing other property as default value of a property?
Hi all,
I am trying to set a property called SQLSERVER like below. What I am trying
to
do is that I take registry value as its value if exist. If it doesn't exist,
I
should take computername as default value. And user should be able to
override
this value by specifying it in msiexec.exe's command line.
<Property Id='SQLSERVER' Value='[ComputerName]'>
<RegistrySearch Id='RepositoryLocation'
Key='SOFTWARE\MyCompany\MyProduct\MyVersion\MyComponent'
Name='RepositoryServer'
Root='HKLM'
Type='raw'
/>
When I build this, I get exception like below:
Myserver.wxs(50) : warning CNDL1077 : The 'SQLSERVER' Property contains
'[ComputerName]' in its value which is an illegal reference to another
property. If this value is a string literal, not a property reference,
please
ignore this warning. To set a property with the value of another property,
use
a CustomAction with Property and Value attributes.
I am trying to figure out I can do this by using CustomAction, but adding
below
generates another compilation error:
<CustomAction Property='SQLSERVER' Value='[COMPUTERNAME]'/>
candle.exe : error CNDL0001 : Cannot set column 'Action' with a null value
because this is a required field.
Can someone kindly teach me how I can solve this?
Thanks,
Sunghwa
