The whole reason I mentioned the RegEdit is because you are using RunTime. The info in post #11 looks to be correct. Here is some additional info. One thing youi might want to do is verify the correct RT was downloaded and installed. I have never installed RT or even Access on a server platform. When I install Access and or RT I make sure to install the 32 bit version. Perhaps this is a snag in your situation.
