Charles,

VFP looks in the following places for the runtime support files:

* Local folder
* System folder next
* Common folder (or whereever vfp9r.dll was registered)


The Service Pack updates will look for updates in Common (or registered) folders and System (I think) and update those.I suspect that you had the runtimes installed inthe system folder and the SP update then updated that version. Ideally you should remove all versions of the runtimes, then reinstall them properly in one place.

Barring that the safe solution is what Sergey suggested - put them into the application folder. THat way you're guaranteed the right version.

>Here is my situation. We need to install two software from different vendor on a same machine. The two software are written in VFP9 : but one use SP1 and the other use SP2. We install the "SP1", runs it and every things is fine. Then we install the "SP2", runs it and everything is also fine. But when we try to run again the "SP1" we get a C0000005 Error.

Is there a way to tell the SP1 version to continue loading its version of vfp9r.dll wich is located in the "system32" directory instead of "common files".
