Error when PC users try to open My OSX created PDF

[Anonymous]

I have created a 3 page(24x36) PDF for a project we are working on. The PDF opens fine on anything I try to open it with on my mac. I have sent it to two PC users that get an error message when they try to open it. They get an "error opening a page" message and page one is blank when it "opens" I guess the other two pages are fine. So, it seems like it is a page one problem. Page one has an imported AC drawing and the same master sheet as the other pages. The diffrence is that page one has two tiffs(LZW pc compression) and some text that I cut and pasted from Word. I have made a test sheet without the imported text and it didn't help. Any ideas?

So I found out what the problem was. The PC users I sent the PDF to did not have the latest Adobe Reader. This should have been an obvious thing to ask, but for what ever reason it took a while to get there.

I did find out that it was one of the TIFFs that was the problem. It was a hidden line view that I had taken through Photoshop to get a good TIFF. I don't have any proof of this, but I think it might have had something to with transparency in the TIFF. The second TIFF on the sheet did not. Anyway, the answer was an end user issue.
