Sources of PTN Problems

Frequent PTN Opening Issues

Nuance PaperPort 14 Removed

Double-clicking your PTN file prompts the message "%%os%% Can't Open PTN File". Customarily, this means that Nuance PaperPort 14 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: If you know of another program that can open your PTN file, you can try opening it by selecting the application from the programs listed.

Obsolete Version of Nuance PaperPort 14

It is possible that your version of Nuance PaperPort 14 isn't able to open your PaperPort Thumbnail File file due to incompatibility. If you do not have the proper version Nuance PaperPort 14 (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is predominately due to having a PaperPort Thumbnail File file version that was created by a newer version of Nuance PaperPort 14 than what you have installed on your PC.

Tip: Sometimes you can get a clue about the version of PTN file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Ultimately, most of the difficulties opening PTN files are due to having the wrong version of Nuance PaperPort 14 installed.
