Troubleshoot ACCESSOR Files

Common Problems Opening ACCESSOR Files

Microsoft Visual Studio Removed

When trying to open your ACCESSOR file, you get the error "Can't Open ACCESSOR File Type". Customarily, this means that Microsoft Visual Studio is not installed on %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: Another ACCESSOR-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Outdated Microsoft Visual Studio

Occasionally, you might have an outdated version of Microsoft Visual Studio installed that's incompatible with your Microsoft Visual Studio Accessor File type. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Visual Studio. This problem is predominately due to having a Microsoft Visual Studio Accessor File file version that was created by a newer version of Microsoft Visual Studio than what you have installed on your PC.

Tip: If you right-click on your ACCESSOR file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Ultimately, most of the difficulties opening ACCESSOR files are due to having the wrong version of Microsoft Visual Studio installed.
