Question:

How can I fix the error that DaVinci Resolve requires 64bit Windows when I have a 64bit system?

I accidentally deleted some System32 files related to DaVinci Resolve when I moved the media cache to a new drive. Since then, I cannot install the latest version of DaVinci Resolve, even though my OS and the previous version of DaVinci Resolve work fine. I wonder if reinstalling DaVinci Resolve will restore the missing System32 files and solve the problem. I also wonder if deleting some System32 files can change my system from 64bit to 32bit, even though my system specs still show 64bit.

Answer:

DaVinci Resolve is a popular video editing software that runs on Windows, Mac, and Linux platforms. It requires a 64bit operating system to function properly. However, some users may encounter an error message that says DaVinci Resolve requires 64bit Windows when they try to install or update the software, even though they have a 64bit system. This article will explain the possible causes and solutions for this error.

What causes the error?

One of the possible causes of the error is that some System32 files related to DaVinci Resolve are missing or corrupted. System32 is a folder that contains essential system files and drivers for Windows. Some of these files are specific to certain applications, such as DaVinci Resolve. If you accidentally delete or modify these files, you may cause the application to malfunction or fail to install.

Another possible cause of the error is that your system registry is corrupted or outdated. The registry is a database that stores information and settings for Windows and applications. It tells the system how to run and configure the applications. If the registry entries for DaVinci Resolve are incorrect or missing, the system may not recognize the application as compatible with 64bit Windows.

There are two main methods to fix the error: reinstalling DaVinci Resolve or repairing the system registry.

Can deleting some System32 files change my system from 64bit to 32bit?
