Thanks Dido for your help,
regarding the first question I should explain that my problem is when i build my installer, and I use the vis of the database toolkit .When I install my application all works fine with exception for those task that executes the vis of database toolkit. I have followed the recommendations of NI and that contained in the manual of database toolkit, chap. 6. without positive results.
With regard to the second question, besides includes the files rpt, I should include some installer od Crystal Reprots? if it is the way, how can I obtain it?
Thanks in advance
Julio
