File holding Add/Remove Programs text?

Last Modified: 2010-04-13
I'm looking to find the actual file that holds the information which Add/Remove Programs loads. Ie how it populates the names and sizes of all the programs installed. I need to find this file as I am writing a program to check version'ing on multiple programs. Yes I'm aware I can do cmd.exe ProgramName -version, as I'm able to do this for most. However for example MSXML cannot be version'd in any normal way( i.e. I can figure out that a MSXML 4.0 folder exists in C:\Program Files\ , but this doesn't tell me whether it's SP2 or not, I've only found that information available in Add/Remove Programs under its listing).

I've found a registry key

That has a key called DisplayVersion with the value of 4.20.9818.0. This is what i'm looking for. However I'm highly doubtful that the exact location in which I found this will be universal for all machines. Crawling the entire registry with a script probably isn't very fun either.

I think it's in the registry


all the keys below that relate to software.  If you delete one of the values below that they disappear from add/remove programs.
There are values within the software key called Version, VersionMajor,VersionMinor which I think is what you are looking for.

>Title: File holding Add/Remove Programs text?

there is no text file, but there are several files which make up the registry which contains the "Add/Remove Programs" list

Ok so it seems HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
is where I need to look, however, is there a way I can create the hash dynamically so that I know what its name is?
ie instead of parsing through tons of keys in \Uninstall\ is there an algo where the hashstring (ex 4302B2DD-D958-40E3-BAF3-B07FFE1978CE ) is created that I can utilize?

Not really this is done by the OS and the installer.  You'll notice some programs have keys others are guids.  You are pretty much stuck with that.  I would suggest renaming the keys as it might break things.
