What are lpsolve55.dll Error Messages?

Dynamic Link Library lpsolve55.dll Errors

lpsolve55.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like lpsolve55.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. OpenOffice.org Portable) could share the same lpsolve55.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when lpsolve55.dll is attempted to be loaded either when OpenOffice.org Portable is starting up, or in some cases already running. Some of the most common lpsolve55.dll errors include:

Access Violation at address - lpsolve55.dll.
lpsolve55.dll could not be found.
Cannot find C:\OpenOfficePortable\App\openoffice\program\lpsolve55.dll.
Cannot register lpsolve55.dll.
Cannot start OpenOffice.org Portable. A required component is missing: lpsolve55.dll. Please install OpenOffice.org Portable again.
Failed to load lpsolve55.dll.
The application has failed to start because lpsolve55.dll was not found.
The file lpsolve55.dll is missing or corrupt.
This application failed to start because lpsolve55.dll was not found. Re-installing the application may fix this problem.

Your lpsolve55.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with OpenOffice.org Portable), or deleted by a malware infection. Furthermore, lpsolve55.dll file corruption could be caused from a power outage when loading OpenOffice.org Portable, system crash while loading lpsolve55.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix lpsolve55.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your lpsolve55.dll issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the lpsolve55.dll error, please proceed to the Step 2 below.

Step 2: If recently installed OpenOffice.org Portable (or related software), uninstall then try reinstalling OpenOffice.org Portable software.

You can uninstall OpenOffice.org Portable software by following these instructions (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
In the search box, type "Uninstall" and press "ENTER".
In the search results, find and click "Add or Remove Programs"
Find the entry for OpenOffice.org Portable 3.2 and click "Uninstall"

OpenOffice.org Portable 3.2

PortableApps

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many lpsolve55.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".
In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
If updates are available for download, click "Install Updates".
After the update is completed, restart your PC.

If Windows Update failed to resolve the lpsolve55.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

If Those Steps Fail: Download and Replace Your lpsolve55.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate lpsolve55.dll file version. We maintain a comprehensive database of 100% malware-free lpsolve55.dll files for every applicable version of OpenOffice.org Portable. Please follow the steps below to download and properly replace you file:

Copy this file to the appropriate OpenOffice.org Portable folder location:

Windows 10: C:\Program Files\LibreOffice\program\
Windows 10: C:\OpenOfficePortable\App\openoffice\program\
Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve lpsolve55.dll problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

CAUTION : We strongly advise against downloading and copying lpsolve55.dll to your appropriate Windows system directory.
