What is your operating system? XP/Vista/Win7/Win8?
If it's Vista/Win7/Win8, then you need to install the 777 using the "Run as administrator" option. Right mouse click on csx772_1200.exe and select "Run as administrator" from the list that pops up.

Were is FSX installed? In the default location (C:\Program Files or C:\Program Files (x86))?
If your OS is Vista/Win7/Win8 AND FSX is installed in the default location  (C:\Program Files or C:\Program Files (x86)), then FSX itself might need to be run using the "Run as administrator" option as well. To make FSX always run as an administrator, go to the FSX root folder, right mouse click on fsx.exe, select Properties, click on the Comparability tab, checkmark (place a tick in) the box Run this program as an administrator (under Privilege Level). FSX will always run with administrative rights, which might prevent it from crashing.

Hope this help
