Send Event to Open PDF - Works on one PC but not on another?

[James Pearson]

Hi everyone, looking for a bit of help please. I'm developing a database using FileMaker 11 Advanced.

I have a button that fires a Send Event to open an external PDF document using a network path. This works perfectly on one PC (a Windows XP laptop) but it doesn't work on my Windows 7 Desktop. The 'Last Error' is 3 on the Desktop. This only seems to affect PDF files and not Word Docs, JPGs, etc, which open without an issue on both machines.

This makes me think that it could be a file association issue or something? However, I am able to double-click a PDF on the Desktop and it will successfully open in Acrobat. Does Filemaker rely on Internet Explorer somehow?

Any suggestions please?

Edit: I tried adding "AcroRd32.exe " to the beginning of the path to the file and it works, but then that's no good for files that aren't PDFs. It proves that the path is correct and that it is possible to open PDFs. So what's going wrong?
