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?

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. Regards, Prantik ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
