This primarily happens when Pervasive has not been installed on the computer, but can also happen if System 5 is installed without local administrative privileges. This DLL file is necessary for System5 to start. See image below:

How to fix?

First, check if Pervasive has been installed on the machine. Most of the time, System5 should work after PSQL installation. However, there are instances, especially Windows 8 and Windows 10, that even though PSQL has been installed already, you will still get this error. Rarely, this also happens on lower tier Windows OS.

Here’s what you need to do:

1. Right click on ‘My Computer’ or ‘This PC’ for Windows 8 and Windows 10 and go to Properties 

2. Go to Advanced Settings


3. Then, click on ‘Environment Variables’.


4. Under ‘System Variables’, look for ‘Path’. Highlight it and edit.


5. For Windows 8 and Windows 10, click on ‘New’ and add the directory for pervasive: C:\PVSW. Click ‘OK’ and close out all windows. You should be able to access System5 after doing these steps.

For Windows 7 and earlier, after editing the Path, you will see a long line of directories. Just go to the end of the parameter and add a semicolon (;) followed by a single space then the directory C:\PVSW\ or C:\PVSW\bin\

C:\Program Files (x86)\Intel\iCLS Client\; C:\Program Files\Intel\iCLS Client\; C:\ProgramData\Oracle\Java\javapath\; C:\PVSW\
