Question: When trying to update Quickbooks, I get an error message that says Error 15271 – a file cannot be validated. This is an error that has plagued many of my clients. The answer on the Quickbooks site is to reset the updates and, failing that, to reinstall the program. This takes a lot of time, and I have found a simpler solution for this and other QuickBooks update issues.
Follow these steps to resolve most Quickbooks update issues:
a) Close QuickBooks
b) Right Click on the Quickbooks desktop icon and choose Run as Administrator
Quickbooks should inform you that there is an update waiting for you to install.
