In my installer I have checkbox "Add also addiotional parameters" with
property ADDITIONAL_PARAMS. Its value "1" if checkbox is checked, and no
value if unchecked.
Worked perfectly, but there are problems. I store property to the registry,
and use regsearch to restore it during upgrade or reinstall.
<RegistryValue Id="ADDITIONAL_PARAMSstore" Root="HKLM"
Key="Software\Company\Installation" Name="ADDITIONAL_PARAMS" Type="string"
Value="[ADDITIONAL_PARAMS]" />
.....
<Property Id="ADDITIONAL_PARAMS" Secure="yes" Value="1" >
<RegistrySearch Id="ADDITIONAL_PARAMS_RS" Type="raw" Root="HKLM"
Key="Software\Company\Installation" Name="ADDITIONAL_PARAMS" />
</Property>
Problem if checkbox was unchecked during first installation. In registry we
see key value of Software\Company\Installation\ADDITIONAL_PARAMS is null. It
is ok: the property value in installer is also null and it is right.
But during reinstall the checkbox become checked! Installer ignored that
ADDITIONAL_PARAMS = null! May be it looks into registry, find no value and
set default value from Property Value attribute?
if I delete this attribute ( <Property Id="ADDITIONAL_PARAMS"
Secure="yes">) then it correctly restored checkbox value (property value)
from registry, but then during first install this checkbox become unchecked
for default! But I need it to be checked for default. What can I do?
