AcroPDF will not display some files after the most recent update.

[LaGatorVII]

I have an application using AcroPDF after the most recent adobe update the program will not open some files. Possibly due to special characters in the file path.

One example is O:\AP_01\@@@\@@#\@=&\00086717.pdf

The I am using the LoadFile() function. This worked fine just last week.

Is there any fix for this issue?

Thanks in advance
