Need a consultation

Hello Guys...

I'm not that good at crystal reports, but I have the following question...

My company has a product the generate an immutable reports, those reports can't be edited or changed at all. Some of our clients sometimes ask for special reports that is not supported by our product, so I need a way to use crystal reports to generate this report and make it available for our clients in a separate application (web or windows application) without the use of visual studio.... thanks.
