• Generation error message PDF: cannot open the file for the generation of a frame (Version 7.2) PDF book

  Hello

  I'm transforming a book in PDF and I get the error message unable to open a file (... < Filename > FM) and the dialog box unavailable fonts also appears. The tricky thing is that I converted the same book in PDF just a couple of days. Now, when I tried to do it again, I'm getting the above mentioned error message. I have tried if you deselect the file > Prefrences > General > remember checkbox missing fonts too. However, it did not help to generate the PDF file. I will be grateful if someone offers a workaround solution for this issue. Thanks in advance.

  Usually, deselection Remember lack of fonts work.

  The missing fonts message when you or FrameMaker opens the file. The solution is to open all the files in the book, or at least those with the "missing" font, clear the message for each file. Now print the book in PDF format, while keeping open files. It usually works because you already erased the messages of missing fonts.

• Error message - Windows cannot open this file after downloading program

  After several days in offline mode, I went online to update Microsoft Security Essentials and click on analysis complete.  It took an hour.  After that, I found that all my programs were virgins, almost of all of the standard microsoft Microsoft Security Essentials is.  I tried to download it again, plus others such as adobe acrobat, but all said "windows cannot open this file".  I asked help from Microsoft but received access denied.  I feel like an illegal immigrant, as all the doors were closed.  What does that mean?  My OS would be illegal?  It is Windows XP and was purchased new in the retail price in 2004 and has only once been out of my hands when I sent it repairs and have 2 GB ram added.  Any ideas?

If I close the window, the message does not appear in the sent folder. I must tell you that I've been using Thunderbird for several years now. Since yesterday, it was working fine. Now it isn't and that left me scratching my head.

• Error message "Windows cannot open this file" for all .exe files.

  I have talked with agents of cat and directly by e-mail to a person called Betty to and followed the steps all the recommended without correcting this problem. I can only run a .exe file in a folder. Any attempt to run an exe from Windows XP - Pro results in a box with the above mentioned error. He also said "to open this file, Windows needs to know what kind of program created." It is now more than a month to get this resolved. It only allows me to easily perform some maintenance and even investigations when necessary. This is the only problem I have with my system. I used AVG 2011 to clean my system to any virus or Trojan horse, and he pointed out that there is no intrusion. This sounds like there should be a simple solution because nothing else is affected. I am very frustrated not to find a solution after such a long time.

  If you are sure that your system is clean of any virus and you have tried the steps mentioned to restore registry and still not be able to open any exe file you can try the method below:
