Writing values from a text file to the registry

[tomriley]

I have added a text file to the project as a support file, and intend to use it to configure the set of registry values that will be written on install (by storing values in this file as a comma separated list Type, Key, Name, Value.

I am currently using the following script to do this:

Set Variable REGISTRY_ENTRY to
Set Variable REGISTRY_ENTRY_EOF to
Set Variable REGISTRY_TYPE to
Set Variable REGISTRY_VALUE to
Set Variable REGISTRY_KEY to
Set Variable REGISTRY_DATA to
label: READ_REG_FILE
if Variable Remove not Equals TRUE
Read from Text File $SUPPORTDIR$\\RegistrySettings.txt into Variable REGISTRY_ENTRY (get EOF into REGISTRY_ENTRY_EOF)
Parse String $REGISTRY_ENTRY$ into Variables REGISTRY_TYPE and REGISTRY_ENTRY (Split at first occurrence of pattern)
Parse String $REGISTRY_ENTRY$ into Variables REGISTRY_KEY and REGISTRY_VALUE (Split at first occurrence of pattern)
Parse String $REGISTRY_VALUE$ into Variables REGISTRY_VALUE and REGISTRY_DATA (Split at first occurrence of pattern)
if Variable REGISTRY_TYPE Equals String
Write Registry Key HKCU\\$REGISTRY_KEY$\\$REGISTRY_VALUE$, $REGISTRY_DATA$
end
if Variable REGISTRY_TYPE Equals Int
Write Registry Key HKCU\\$REGISTRY_KEY$\\$REGISTRY_VALUE$, $REGISTRY_DATA$
end
if Variable REGISTRY_TYPE Equals Binary
Write Registry Key HKCU\\$REGISTRY_KEY$\\$REGISTRY_VALUE$, $REGISTRY_DATA$
end
if Variable REGISTRY_ENTRY_EOF Equals FALSE
GoTo Label: READ_REG_FILE
end
end


This looks to me like it should work, but when I run it, only the last line of the file is actually written to the registry. Does anyone know why this is?

This is because you cannot loop Windows Installer commands in the setup script - please read this whitepaper for information:

Thanks for that. Does anyone know a method of reading the registry values from a configuration file so that I don't have to import entries from my registry every time I make a change?

You can just merge a .reg file silently at install time.

Thanks again. Any chance of a few pointers on how to do this? I've looked in the help and not managed to find anything.

Use Run Program with regedit to silently merge the .reg file with your registry. The silent parameter might be /s or /y - a quick Google search should reveal this information for you.
