Error Previewing File when importing delimited file metadata

[devanpeebles]

When attempting to preview data while importing the meta data for a delimited file I get the following error.

My studio is version 7.2.1

JRE is 1.8.0_171

null
Preview error. Some settings must be changed.
Note: Preview errors are generally due to a wrong encoding setting.

Have you tested other files? Always has the error or the problem only occurs for this file? I have seen the same issue reported before, it is caused by the studio installation. Can you show the installation path of studio?

I have studio installed in C:\Talend\TalendStudio\

And yes it seems to do it with any file I try to preview.

Ah... yep looks like my studio install got corrupted at some point.

Would be nice if there was a way to fix that without reinstalling.

If the installing got corrupted, It is recommended to reinstall studio to make sure the studio works smoothly.
