Sources of VPI Problems
Common VPI Opening Problems
Virtual Pascal Isn't There
If you attempt to load your VPI file, you experience a message such as "Can't Open VPI Files". When this happens, it is commonly due to Virtual Pascal missing in %%os%%. You won't be able to double-click to open your VPI because your OS doesn't know what to do with it.
Tip: If you know of another program that can open your VPI file, you can try opening it by selecting the application from the programs listed.
Virtual Pascal is Out-of-Date
Occasionally, you might have an outdated version of Virtual Pascal installed that's incompatible with your Virtual Pascal OS/2 Unit File type. Installing the latest version of Virtual Pascal from Allan Mertner is recommended. This problem is predominately due to having a Virtual Pascal OS/2 Unit File file version that was created by a newer version of Virtual Pascal than what you have installed on your PC.
Tip: Right-clicking on your VPI, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Conclusion: The majority of VPI file opening issues are due to not having the correct Virtual Pascal version installed.
More Causes of Problems Opening VPIs
Even with the correct version of Virtual Pascal installed, you can still experience difficulties opening VPIs. There can be other issues - unrelated to software - preventing you from opening VPI files. Issues that aren't software-related:
- Invalid VPI file references in the Windows Registry (the "phonebook" of the Windows Operating System)
- Deletion of the VPI file description from the Registry by mistake
- Corrupt install of Virtual Pascal or other VPI-related program
- Your VPI file is corrupted (issues with your Virtual Pascal OS/2 Unit File file itself)
- VPI file integrity has been compromised by malware
- Device drivers for VPI-related hardware are out-of-date
- Windows has inadequate resources to open your Virtual Pascal OS/2 Unit File file
