What are app-build.js Error Messages?

app-build.js file errors often occur during the startup phase of AVG PC TuneUp, but can also occur while the program is running. These types JS errors are also known as “runtime errors” because they occur while AVG PC TuneUp is running. Here are some of the most common app-build.js runtime errors:

Download app-build.js Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying app-build.js to your appropriate Windows system directory. AVG Technologies typically does not release AVG PC TuneUp JS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing app-build.js and all other JS files for AVG PC TuneUp. An incorrectly installed JS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
