Understanding 850 Issues

Common Problems Opening 850 Files

Microsoft Visual FoxPro Disappeared

You encounter an error message such as "%%os%% Can't Open 850 Files" when trying to open your 850. 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. This will prevent you from double-clicking to open the 850 file because the OS doesn’t know how to handle it.

Tip: When another 850 application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Incorrect Microsoft Visual FoxPro Version

Sometimes your installed version of Microsoft Visual FoxPro won't support your Visual FoxPro 98 Data 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. The primary cause of this problem is that your Visual FoxPro 98 Data file was created by a different (newer) version of Microsoft Visual FoxPro than what's installed.

Tip: Sometimes you can get a clue about the version of 850 file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Summary: In either case, the majority of problems opening 850 files are related to not having the correct software application installed on your computer.

Other Causes of 850 File Opening Problems

Assuming you have the right Microsoft Visual FoxPro version installed, other problems can prevent you from opening 850 files. Other 850 opening errors can be created by other system problems inside of %%os%%. These issues include:

• Invalid 850 file references in the Windows Registry (the "phonebook" of the Windows Operating System)
• Accidental deletion of the description of the 850 file in the Windows registry
• Microsoft Visual FoxPro or another 850 application experienced a flawed installation
• 850 file corruption
• 850 file integrity has been compromised by malware
• Hardware associated with 850 has outdated drivers
• Too many applications are open on your PC to load your Visual FoxPro 98 Data file successfully
