When you add a class dll, it gets appended to the end of those which
preceded it (many of them inbox). When you reinstall with the new INF, you
should be seeing your “DevPropSheet.dll” getting appended as well. However,
when SeupAPI parses these definitions to find the dll to utilize, it appears
to do so in a left to right fashion. Thus, it will find your old
“TestDevPropSheet.dll” before your new one.
To fix, uninstall your driver, search registry for “TestDevPropSheet.dll”
and edit the string variable to remove ONLY that reference from the string,
leaving those definitions preceding it still there.
