I am using the Microsoft Setup Toolkit to develop a new installation
procedure for our Windows 3270 product.  I have run into a problem 
creating the program manager group.  First time the install is run, no
problems.  The second time, each icon is added again.  I am using the
cmoOverwrite option to CreateProgmanItem with Windows 3.1.  According
to the manual (page 59), this should cause program manager to replace
the icons, not duplicate them.  This behavior can be reproduced with the
simple setup program:


'**************************************************************************

'$INCLUDE 'setupapi.inc'
'$INCLUDE 'msdetect.inc'

INIT:

'* Create program manager group
    CreateProgmanGroup "Test", "", cmoNone
    ShowProgmanGroup "Test", 1, cmoNone
    CreateProgmanItem "Test", "Test", "TEST.EXE", ",,,,", cmoOverwrite
    
QUIT:
    end
    
Run this twice and the Test icon will be duplicated in the Test group 
instead of being overwritten the second time.

Has anybody else ran into this problem?  If so, is there a workaround?

Since there is no way to check if the items exist or to delete the group
from the setup program, there does not seem to be a way around this
other than writing a C function to perform the DDE conversation with
program manager to delete the group and calling that C function from
the setup program.
