upx error

Problem: upx fails to pack an executable under (at least) Windows 7 64-bit OS

symptom: message upx: [exe name] IOException: file is write protected -- skipped

solution: update upx to later version from http://upx.sourceforge.net/

Compatibility mode not so compatible

I received the message below when re-starting Google Chrome:

This application was unable to start correctly (0xc00000a5). Click OK to close the application)

It turns out that it fails because I had it set to Windows XP 'compatibility mode' in Windows 7. I did that because Chrome kept crashing and I thought setting it back to a lesser version might be the cure. I was wrong.

The fix: Find the icon for Chrome, right-click, choose 'Properties' and then the 'Compatibility Tab' and uncheck 'Run this program in compatibility mode". Save and go on your way.

Note: If the checkbox is grayed out (disabled), use the 'Change settings for all users' button and set it there.
