install without messages
Posted 11 October 2001 - 09:16
could anyone tell me how I would go about installing on a client machine and specifying I do not want any messages displayed to the user. At the moment I am getting messages for some of my dlls which say "This dll is protected by windows and cant be installed". If you ignore it thats fine, but I do not want the user to see these messages. I tried to put a condition of NOT INSTALLED on the dlls with the problem, but to no avail I still got the messages.
Anybody know what I could do??
I appreciate any replies

Installed is a property that contains the time of the last installation of a product so it can be used to detect maintenance installations. This property is not defined for new installations so "Not Installed" will always be true.
Firstly you should look for merge modules for third 3rd party files. The better ones check for the presence of themselves.
For the other files you will might use AppSearch to set a property for a particular component. I think it is better to look for a related registry key rather than the file itself.
For some dlls you can simply use a test on operating system because it is safe to assume the dlls are already there for later operating systems. (and older operating systems do not have file protection).

Devang, i know how to put a condition on a component but how do I get it to change its level to 150?
Thanks, I still have a lot to learn at this lark!

A feature condition assigns an install level to a feature. There is also an Install level for the package. If a feature has a higher value than the level of the install then the feature is not installed. The custom setup dialog still allows selection and installation of this feature.
A feature is also not installed if its install level is zero. In this case it is hidden in the custom setup dialog.
I think you are better off with simple conditions on components.

I tried to put a condition on the component VersionNT < 500. My thinking was that if the clients machine was less than a Windows 2000 OS, the components would be installed otherwise it would nt be installed. However when i tested this on a windows 2000 machine, i still got the message saying these are windows protected files.
Is there something else i need to do to set a condition?
Also, are all the files associated with an OS listed anywhere so that I could check which files I dont nedd to install or not?

Try "VersionNT And VersionNT=400 Or Version9X"
What does the log say. After install validate I would expect something like
MSI (s) (B4:EC): Component: VCDservD.PDR; Installed: Absent; Request: Local; Action: Null
As to a list of files under file protection, take a look at <windowsdir>\system32\dllcache. This usually contains version of protected files ready for restoration. (There can be others).
