PHP and Crystal Reports

I am trying to write a php program that opens a number of reports written in Crystal 11. From research on the internet, I found that CR would have to be called using COM.  So I did that. From the command line it triggers a dialog box saying that the version of Crystal the reports was written in was later than the one that is being used to open it via the php program.   The other problem is that when it is run from the browser the program hangs on the openReport command

 

Can anyone assist me on resolving the hanging issue or the entire thing for that matter.

 

Thanks!

 

John
