Hi there! I’ve been recently receiving the following error message upon opening eM Client:
MailClient.exe - System Error
The program can’t start because libmupdf.dll is missing from your computer. Try reinstalling the program to fix this problem.
OK
After I click OK, the program runs normally, but from times to times it shows me this error and I dont understand what could be the problem, could you help me, please?
You don’t say which version you are running, however, first step is to run the latest MSI installation setup this will either update or give you 2 options - chose REPAIR then take it from there.
The latest release version of EM Client V8.0.3385.0 Windows or V8.0.3494.0 Mac
I just scanned my system, I do not have ‘libmupdf.dll’ on my system.
An internet search indicates that ‘libmupdf.dll’ is part of a program named SumatraPDF which presumably is or has been installed on your system.
To resolve the issue you will probably need to reinstall or repair SumatraPDF
I also have the problem of EMClient indicating that the file libmupdf.dll is missing. As the first post here indicated the message that EMclient can’t start because of that file missing appears regularly on my laptop, even when EMClient is in fact up and running. I do NOT have SumatraPDF installed, and never had. So to me this is clearly an EMClient error. And related to version 8; it never happened with version 7. Reinstalling doesn’t help.
First the error issue with ‘libmupdf.dll’ is not a fault with eMC
Have you investigated the issue of ‘libmupdf.dll’ on the internet?
As I am curious, I have just done another search through GIT and discovered that the file was developed by Artifex Software for Ghostscript
Ghostscript is a suite of software based on an interpreter for Adobe Systems’ PostScript and Portable Document Format (PDF) page description languages. Its main purposes are the rasterization or rendering of such page description language files, for the display or printing of document pages, and the conversion between PostScript and PDF files.
Ghostscript can be used as a raster image processor (RIP) for raster computer printers, for instance, as an input filter of line printer daemon, or as the RIP engine behind PostScript and PDF viewers. It can also be used as a file format converter, such as PostScript to PDF converter. The ps2pdf conversion program comes with the ghostscript distribution.
Ghostscript can also serve as the back-end for PDF to raster image (png, tiff, jpeg, etc.) converter; this is often combined with a PostScript printer driver in “virtual printer” PDF creators. As it takes the form of a language interpreter, Ghostscript can also be used as a general purpose programming environment.
So the resultant is that ‘libmupdf.dll’ is NOT exclusive to SumatraPDF it is used by a host of printers and other stuff. So I guess SumatraPDF was a lucky first hit.
Only you will know what software you have installed and products you use, so I suggest you investigate this further.
Hi, thanks for responding. But it doesn’t explain the error message, which clearly says at the tope: Mailclient.exe - System Error. I guess maybe version 8 is trying to use some of that ghostscript?
Tried that. No change unfortunately. And the recent updated version also didn’t make things any better. Anyway, the main problem remains the way version 8 does the windows management, as per my earlier post: 1) No longer closing all open windows when closing the main EMClient window (a change that I really don’t understand), and 2) freezing when you are in a message composition window and want to go to the desktop via the “Show desktop” button. Also not showing the desktop then. This happens without fail.
