Sources of DPL Problems


Issues Opening DPL Files

Delphi (IDE) Isn't There

If you attempt to load your DPL file, you experience a message such as "Can't Open DPL Files". Usually, this is because you do not have Delphi (IDE) for %%os%% installed. The typical path of opening your DPL with a double-click won't work because %%os%% cannot make the program connection.


Tip: Another DPL-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Delphi (IDE) Requires Update

Sometimes your installed version of Delphi (IDE) won't support your Delphi Package Library file. If you've got the wrong version of Delphi (IDE) installed, you'll need to install the correct version. This problem is predominately due to having a Delphi Package Library file version that was created by a newer version of Delphi (IDE) than what you have installed on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the DPL file, selecting "Properties", and looking at the version information.


Conclusion: The majority of DPL file opening issues are due to not having the correct Delphi (IDE) version installed.


Additional DPL Opening Issues

Assuming you have the right Delphi (IDE) version installed, other problems can prevent you from opening DPL files. Other DPL opening errors can be created by other system problems inside of %%os%%. Issues that aren't software-related:

  • Invalid DPL file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Accidental deletion of the description of the DPL file in the Windows registry
  • Delphi (IDE) or another DPL application experienced a flawed installation
  • Something has caused file corruption of your DPL
  • The DPL is infected with a virus
  • Device drivers of the hardware associated with your DPL file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the Delphi Package Library format
