Not sure what's changed in the configuration of my system, but now my VFP 6.0 (SP5) session hangs whenever when compiling a multi-threaded DLL (on 64-bit Win7 Ultimate). It appears to be hanging just after it announces it is generating the type library. Previously it would get past this point, and would silently fail at stage where DLL was being auto-registered. Now VFP 6.0 session is hanging and the only way to exit is to forcibly halt the process in Task Manager. The auto-registration bit doesn't bother me -- I'd prefer to do the registration of the DLL myself, rather than letting the compiler "automagically" do it for me (at least when I do it manually I'm more certain about the configuration options selected -- if the compiler does it, I'm not sure if it is using the same options that I'd be using in actual install). I have no problem problem when compiling programs to FXP, APP and EXE. I ruled out antivirus (Kaspersky) by suspending its operation when trying the rebuild of DLL (it still hangs with antivius deactivated). Performing the build in VFP 6.0 session started using "run as administrator" would work (but it is likely doing the autoregistration bit, which I'd prefer it *NOT* to do).

On same system VFP 9.0 gives error about not being able to update registry (but that's OK, as I'd prefer to be registering components explicitly rather than compiler "automagically" doing it for me), but the DLL, TLB and VBR are being properly generated. Not seeing any other problem.

Both VFP 6.0 and VFP 9.0 were installed from original discs (along with relevant service packs) on the new computer with 64-bit Win7 Ultimate --- they were *NOT* manually migrated to new system from the older XP Pro system. What generally puzzles me is that as of late, the VFP6.0 is now hanging -- it wasn't doing this before. Anybody else have a similar experience?

I can't really drop VFP6.0 yet -- I still need to be able to support users running older versions of software compiled in VFP 6.0. Speaking of old software... I've got FPW 2.6 set up in a VM (only way to get it to work in 64-bit Windows) -- still have some customers using some really old software -- as they're using some rather ancient hardware, migration to VFP-based software isn't in the cards yet (about the only way they could be convinced to upgrade is when their old hardware eventually fails -- and are forced into upgrading to newer software because the older software won't work on newer OS -- which is will get forced on them because the old OS they've been using won't run on newer hardware anyway).
