I need a custom action that can determine if a folder is read only. I can easily get the "read only" attribute from the folder, but the real problem is that I need to know if the user can write files to a network share or not.

If a folder is on a network share, it may not have its read only bit set, but because of security settings, the folder may be read only.

Any suggestions as to how to go about finding out this?

Take a look at MsiSetTargetPath. Note: (not clearly stated in the docs) You can only call MsiSetTargetPath after CostFinalize.

Take a look here. You should be able to find a script that does what you need. This site is probably the best script resource that I have found.

Another workaround is to write a script that tries to open a temporay file in the network folder in question. If the operation fails then you know that the user does not have write access to that folder.

ok, I'm getting somewhere. I've got a custom action that tries to determine if the path is read only or not, and sets a property to 1 if its read only, 0 if its not.

I also have a non-visible feature in the install, with a condition that changes its install level to 1 if the read only property is 0 (meaning I can write out the files).

However, upon installation, the feature install level is never changed.

So I guess the next question is where in the execution sequence should this custom action go so that the condition on the feature will see it and enable the feature?

It must be insertede before CostFinalize in both UI and Execute sequence (because feature conditions are evaluated during CostFinalize)
