That Calendar control is probably the problem. It sounds like you are not
using the control so remove it from the toolbox in your VBE while the
project is selected. Recompile the project.

I recently designed a Excel UserForm. It ran perfectly on my machine. But
on
another PC it encountered "object not found" problem. I checked the
library
list on the Reference drop down, they are selected the same on both
machines.
One thing is worth to mention that I used the Calendar control on the
design,
which is found on the "Additional Control" drop down on the UserForm
toolbox
on my machine, but not on the other machine. Is this Calendar control
matters
for this error, or something else wrong?

Thanks for your help. I need the help badly.
