>Take a look at Requirements under option 6 and make sure NT is not excluded. Also, you may need to install some additional merge modules, such as GDI+. See http://fox.wikis.com/wc.dll?Wiki~MergeModule~SoftwareEng for more info on that. I've also heard that you need to have the Desktop Update (Active Desktop, etc.) installed on NT for VFP8 to work, but I haven't tested that myself.

Thanks for the replies, guys.

NT is in the Requirements...basically, this is a warmed-over ISM originally built for NT4 installs - so I haven't changed much (added XP to requirements, updated some modules and the GUIDs, and compiled the vfp EXEs into vfp8. Haven't done anything else I can think of.

You may be on the right track about a missing module for NT - I have all the vfp8/XP stuff, but maybe I need to keep an older module (like the older GDI+ version?).

I think my next step will be to manually load the vfp8 runtimes onto NT, and see if a vfp8 exe will run okay. Then we know the trouble is with ISX, and not NT. If not, there may something NT needs, like the Active Desktop you mention.

I'll test it tomorrow...
