Troubleshoot AC7 Files

Troubles Opening AC7 Files

Spice is Not Installed

When trying to open your AC7 file, you get the error "Can't Open AC7 File Type". Customarily, this means that Spice is not installed on %%os%%. You won't be able to double-click to open your AC7 because your OS doesn't know what to do with it.

Tip: If you have another software that you know opens AC7 files, you can select it by hitting the "Show Apps" button.

Outdated Spice

In some cases, you might have a newer (or older) version of a SPICE AC/Frequency Domain Output File file that is unsupported by your installed application version. If you've got the wrong version of Spice installed, you'll need to install the correct version. This problem is predominately due to having a SPICE AC/Frequency Domain Output File file version that was created by a newer version of Spice than what you have installed on your PC.

Tip: You can sometimes get hints about the right program version by right-clicking on the AC7 file, selecting "Properties", and looking at the version information.

Conclusion: The majority of AC7 file opening issues are due to not having the correct Spice version installed.
