My first and subsequent attempts to use the program to convert a file to pdf failed and I received the following error message:
"Run-time error 35613. ImageList must be initialized before it can be used."
My PC runs Windows 7 Home Premium (x64) Service Pack 1 and has all the latest MS updates.
Help please.

This issue has come up once before, but we haven't been able to reproduce it ourselves yet. As it happens, we are currently writing a new Windows interface for Prince that should fix this issue, as well as supporting the latest Prince features and a brand new look.

If the issue persists in the meantime, it should still be possible to run Prince from the command-line, running cmd.exe and then Prince\Engine\bin\prince.exe as described here. You can also run Prince from other software, using the Java/PHP/.NET wrappers.
