Bill L., thanks for the pointer about the icon file directory in Inno Setup; I looked at that file multiple times for other reasons and just missed it. It now works.
I tried instrumenting the code, as you suggested: ======================================================================== myapp_viewdata_button=: 3 : 0 (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01' viewdata'' (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 02' wd'psel myapp;' (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 03' wd 'sbarset idstatusrdy 50 Ready' (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 04' ) ------------------------------------------------------------------------ viewdata =: 3 : 0 (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01a' if. (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01aa' (# 'datasheet' names 0) do. (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01b' grid datasheet (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01c' else. (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01d' wdinfo 'Alert';'Please read legacy data first.' (<'c:/temp/myapp.log') 1!:3~^:DEBUG CRLF, 'check point 01e' end. ) ======================================================================== The log shows ------------------------------------------------------------------------ check point 01 check point 01a check point 01aa ------------------------------------------------------------------------ and I got the error message. That says the system crashed at the (# 'datasheet' names 0) statement. That makes no sense to me. BTW, I changed myapp.ijs to ======================================================================== NB. load jpath'~user\projects\dsm\cilegacy.ijs' NB. load jpath'~user\projects\dsm\ciform.ijs' load 'cilegacy.ijs' load 'ciform.ijs' ciDSM_run'' ======================================================================== in the presumption that it will draw from the pwd. That probably made it possible for it to run on someone else's computer, but it should have no effect on my installation.
