[RESOLVED] ole automation

i have a portable application i wrote 10+ years ago, which i copied on to a computer, where it worked fine, until i installed office, i now get error 68 device unavailable as soon as i try to start the program, i believe it is caused by trying to reference stdole32 version 2, when office has now installed a later version

i see that any new project i start already has a reference to ole automation, is this particularly required? or should it only be referenced when actually needed?

i am sure i can fix the immediate problem, but am interested for future projects, or how to avoid update problems

This has been part of Windows for a very long time. It has been a core part of VB for quite a while, at least VB5 and VB6, probably 32-bit VB4.

See Supported and shipping in Windows.


It seems very unlikely that MS Office "replaced" it with an incompatible version.

Device unavailable (Error 68) doesn't sound like it has anything to do with this typelib.

Hi,

Printer problem ?
