When creating MSI packages we should always ensure that they conform to Windows logo standards and best practises. Adhering to these standards enables us to produce more reliable and well-authored MSI packages.
To perform this compliance check, we usually validate our MSIs using the Full MSI Validation Suite. What this validation process does is validate the MSI tables against certain rules which are specified in a .cub file called darice.cub. As a result of running this validation, we may be prompted with ICE warnings/errors which we should attempt (in most cases) to resolve.
This validation is great, but what if we need to do our own custom validation? For example, Alkane Solutions do work for multiple clients who all have different requirements:
COMPANYNAME (“Customer 1”, “Customer 2” etc)
ARPNOREMOVE (Some like 1, others like 0)
REBOOT (Maybe we just want to ensure that this property exists, and that it is set correctly?)
Some of our clients use Custom Actions to perform certain logic, and we must ensure that these are present in every package we deliver.
Customer-specific naming conventions:
Some of our clients use specific naming conventions for things like the ProductName property. Some like to limit the number of periods in the ProductVersion.
In-house validation checks:
We like to check that our tables do not contain hard-coded paths, that we only append to (and not overwrite) the Path environment variable, that services use the ServiceInstall/ServiceControl tables and not the registry table, and that TNSNames.ora is not included with any package.
But how can we perform these validation checks when we have no scripting knowledge, and no knowledge of .cub files?
Easy – that’s where CubMakr comes in.
CubMakr is a custom toolset written using the Wix DTF (Deployment Tools Foundation) with the aim of generating custom CUB files to validate your MSI packages. No scripting knowledge is required!! CubMakr should be used to generate a CUB file which reflects the packaging standards that your company/client adheres to. Using it will:
- Increase Accuracy of Packages
- Reduce Errors
- Improve Quality and Reliability
- Reduce Packaging Time
Here are a list of features:
- Validate ANY table, and ANY column
- Validate the Summary Information Stream
- Multiple search comparison operators such as ‘equals’, ‘contains’, ‘starts with’ and ‘end with’
- Search using regular expressions!
- Perform case-sensitive searches!
- Resolve property names at validation time
- Display custom messages!
- Set conditions for each validation rule!
- Display warning, error, info or failure ICE messages!
- Re-order the rules you create, so messages are displayed in a specific order!
and here is an example of things that can be validated for:
- Check that certain values exist – this could be a property/value pair, a registry key, a launch condition, a custom action….or anything else contained within a Windows Installer
- Check the format of an entry is correct – for example, check that the ProductVersion property is of the form major.minor.build
- Check for hard-coded paths
- Check that the case of an entry is correct – for example, check that GUIDs are upper case and check that specific public properties are upper case
- Check that files exist/don’t exist – for example, ensure that files such as TNSNames.ora/hosts/services are not captured.
- Check that services use the ServiceInstall/ServiceControl tables instead of the Registry table (where possible)
- Detect if a driver installation has been captured, and warn the user that it must be configured accordingly
- Detect for darwin descriptors
- Detect for junk files/registry which needs excluding
- and much, much more…
Since the first release is just a BETA (to see if people find it useful), we have not included a way of saving cub files and retrieving them at a later date. Unfortunately whatever cubs you generate are only persistent for the current browsing session. The long term goal would be to enable people to save cubs for each client/project.
