How to fix script Errors

I install crystal 11 on Windows 7 machine and getting:

An error has occurred in the script on this page

Line 16

Char 3

Error Library not registered

Code 0

URL file:///c:users/trust?/appdata/local/temp/prompton1.html

Do you want to continue running scripts on this page?

I'm trying to export out to .pdf file and no matter what I click it's not working properly.

It runs fine in XP is there something that didn't get installed correctly. I have tried uninstalling

and installing again and still same message.

Any help would be great

Thanks
