[Wine] PDF problems in wine

[Z.K.2]

Okay I installed FreePCB and it works fine, but under the help documents there are selections to some pdf files and when I click on one of these pdf file selections wine tells me there is no program associated with the pdf files.  I installed a windows pdf reader, but get the same error.  So I was wondering how to tell wine to use the pdf reader I installed or even the native linux pdf readers.
