How to Fix Prop Res DLL not loaded

Printer errors care be really frustrating, not only because they prevent you from getting the presumably important documents you were trying to print, but also because it’s hard to tell if the problem is with the computer or the peripheral device. One such error message people have encountered while trying to print a file in Microsoft office is:

Cannot load Library DLBAPRP.dll
Prop Res DLL not loaded

This post will show you what to do if see it.

First of all, you should know this isn’t a problem with Microsoft Office. Rather, some printer driver DLL files are missing, and since the device can’t find them it will not work properly. You will have to get the files manually by following these steps:

1. Firstly, run these Microsoft Fix it’s:

2. Then copy the printer driver files to the System32 folder:

  • If you are using 32bits computer use the following path
    • C:\Windows\System32\Spool\Drivers\W32X86\3
  • If you are using 64bits computer use the following path
    • C:\Windows\System32\Spool\Drivers\X64\3

3. Copy all of these files one by one and paste them into C:\Windows\System32

  • dl**prpr.dlll
  • lx**prpr.dll
  • lx**prpb.dll
  • dl**prpb.dll

You should copy every file you see that looks like the files above. The ** stands for a couple of letters specific to the printer.

C:\Windows\System32\Spool\Drivers\X64\3 (for a computer running a 64-bit Windows operating system)
