1ST Troubleshooting


Frequent 1ST Opening Issues

Microsoft Visual FoxPro is Not Installed

When trying to open your 1ST file, you get the error "Can't Open 1ST File Type". If this is the case, it's usually due to the fact that you do not have Microsoft Visual FoxPro for %%os%% installed on your computer. 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 don't have Microsoft Visual FoxPro installed, and you know of another program to open your 1ST file, you can try opening it by selecting from the programs listed under "Show Apps".


Obsolete Version of Microsoft Visual FoxPro

Sometimes your installed version of Microsoft Visual FoxPro won't support your Visual FoxPro Documenting Wizard List file. If you do not have the proper version Microsoft Visual FoxPro (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 most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Sometimes you can get a clue about the version of 1ST file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Conclusion: The majority of 1ST file opening issues are due to not having the correct Microsoft Visual FoxPro version installed.


Other 1ST File Opening Causes

Even with the correct version of Microsoft Visual FoxPro installed, you can still experience difficulties opening 1STs. If you are continuing to have errors with loading 1ST files, other external issues might be to blame. Other contributing causes:

  • File references in the Windows Registry for 1ST are wrong
