Ista error

If you've installed it manually there should also be a text file somewhere called *.reg included with the source files for programming mode. You'll need to make sure all these entries are merged into the registry, or add them yourself manually. Or if you open these files you can then view the registry entries in the text file and check they are all in place by viewing your registry. This is the kind of thing you're looking for....
"BMW.Rheingold.Programming.ExpertMode"="True"
"BMW.Rheingold.Programming.Enabled"="True"
"BMW.Rheingold.Programming.PsdzDataPath"="..\\..\\..\\PSdZ\\data_swi"
You'll also need to have the full copy of psdzdata installed where that path points to.
