Hi All,
I need to search the users' computer to see if some products have been installed. And I use the function MsiGetProductInfo(...) ..I used it like this:

UINT iResult = MsiGetProductInfo(
wszProductName, &dwProductName);
if ( ERROR_SUCCESS == iResult )
MsiSetProperty( hInstall, "InventorView_EXIST", wszProductName );

And I installed 4 product(ALLUser) to test the function.
It works right in 3 products but 1 failed. when I debuged that failed one I found the iResult was set 1605...which means ERROR_UNKNOWN_PRODUCT...The product is unadvertised or uninstalled....But it is not uninstalled! mad.gif
I searched the abnormal product's ProductCode in registry. In the key--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall... it contains all infomation of the product (including DisplayName...I think it is the INSTALLPROPERTY_INSTALLEDPRODUCTNAME I try to get)
And then in the "Add/Remove Programs" entry it can be uninstall successfully.

Do any one knows why function MsiGetProductInfo cannot get the information for me?
Thanks in advance?
