Re: [WiX-users] Where does MSI store installed state
There a couple of questions in this thread. Regarding what's
installed, don't trawl the registry looking for clues, trawl the
documentation instead. MsiEnumProducts() will list what's installed.
MsiGetProductInfo() will tell you details about a specific installed
product, just to use two examples of many. The p/invoke from managed
code isn't too difficult and there are p/invoke libraries out there if
you look. Pinvoke.net can help too:
http://www.pinvoke.net/default.aspx/msi.MsiEnumProducts
Upgrade table: An MSI file is a database you can access and modify
with SQL-like statements. It's basically a matter of using the
appropriate SQL once you get the surrounding framework in place. Start
with this kind of thing:
http://stackoverflow.com/questions/27634407/how-to-get-the-product-version-from-an-msi-file-without-installing-the-msi
and look for other examples that use MsiDabaseOpenView and so on, and
the SQL to delete, add or update tables.

Hi All,
I am trying to find out something. I hope you can help. I was wondering how
does the msi
keep a track of the fact that the product has already been installed. I
will explain the issue in detail.
For eg:- When I install product.msi with
ProductCode={8AFF09B8-EA81-449E-9475-9567E7367314},
it would create an entry in the registry
@HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{8AF
F09B8-EA81-449E-9475-9567E7367314}
specifying the Displayname ,uninstallstring etc. If I delete this registry
key then I do not see the entry for the product in the Add and Remove
Programs.
But if I run the msi again, it prompts for repair, change etc. I was
wondering where is the data stored in the m/c specifying that the
product is already installed if not in the registry. I was wondering if
someone could point me at something.

Re: [WiX-users] Where does MSI store installed state
Hello All,
I found that the entries are in the Windows Upgrade Table.
http://msdn.microsoft.com/en-us/library/aa372379%28v=vs.85%29.aspx
Is there a way to view this table from C# code and add or delete some
entries?
