How to unblock .chm file downloaded from the Internet


Question: I've downloaded .chm file from the Internet. However, when I open the file, I get the message "Navigation to the webpage was canceled".

 Solution: You also can't download .chm files from a web browser and simply click Open.  Download the .chm file to your computer first, right-mouse click it in Windows Explorer and select Properties.  Then click Unblock.

Xerox 116-324 fault when printing .doc or .pdf containing callibri fonts

Image
Problem : You are unable to print .PDF or .DOCX documents which contain Calibri fonts. The Xerox 7345 or similar model sends 116-324 error code and needs to reboot. Resolution : Update you computer with the latest drivers from Xerox website. If you are on PCL driver - disable the Print Optimization feature in the driver. If you are on the PS driver set the PostScript Output Option to Optimize for Portability. The print file will be larger and printing will take more time. Another PS driver setting may screw up the text in your PowerPoint slides (as shown on the picture below). It is "PostScript Pass-through". If you have printouts like on the picture below, you better enable "PostScript Pass-through" (Printing preferences> Advanced> Driver section. )

Problem: Microsoft PowerPoint 2010 may crash while you are copypasting slides or scrolling through them in Slide Sorter view. If you check the Application log in the Event Viewer, you may find something similar to this record: Faulting application name: POWERPNT.EXE, version: 14.0.6009.1000, time stamp: 0x4cc1a4ed Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319 Exception code: 0xe0000002 Fault offset: 0x0000b9bc Faulting process id: 0x5a8 Faulting application start time: 0x01cdc3cbb1c20f5b Faulting application path: C:\Program Files (x86)\Microsoft Office\Office14\POWERPNT.EXE Faulting module path: C:\WINDOWS\syswow64\KERNELBASE.dll Report Id: 484578ef-3244-11e2-88e2-0026b9efd81c Solution : First of all make sure that it happens only to the specific presentation file. Then go to the master and check if you have any graphical elements in it. They are generating 99% of the problems. In my specific case it was Windows Metafile object...
