====== Programs, installs and updates ======

===== A program does not start =====

If it says ''VCRUNTIME140.dll'' or ''MSVCP140.dll'' is missing, install the Microsoft Visual C++ Redistributable. See [[v4:install:requirements|Before you install]].

PBDispatch and PBTerm will not start without ''ssh.dll'' next to them, and ''libcrypto-3'' is needed too. See [[v4:reference:programs|Programs]].

If you use the wrong package for your Windows, programs do not run properly. Use the Win32 package on 32-bit Windows and the x64 package on 64-bit.

===== PBInstall stopped with an error =====

Read the install log in ''LOGS''. If it says the backup failed, nothing else was changed. Fix the cause (usually a full disk or a file in use) and run PBInstall again. See [[v4:install:fresh_install|Installing ProBoard v4]].

===== PBConfig says files are missing =====

On a fresh install, answer **Yes** and let it create them. After moving to v4, the Upgrade Data page opens for you. See [[v4:install:upgrade_16bit|Upgrading from 16-bit ProBoard]].

===== User dates look wrong =====

Use **Repair User Dates...** on the Upgrade Data page. Stop all nodes first. See [[v4:install:upgrade_16bit|Upgrading from 16-bit ProBoard]].

===== An update will not install =====

  * ''ProBoard.exe'' is running. Install when no callers are online, or use the force option knowingly.
  * The release needs **Upgrade Data** first. Run it, then confirm.
  * Read ''LOGS\UPDATE.LOG''. To undo an update, use **Tools > ProBoard Updates > Roll Back**.

See [[v4:install:program_updates|Program updates]].
