MultiPar requires a PC with Windows Vista or later (Windows 7, 8, 10).
Double click setup file ( MultiPar131_setup.exe or something like this name ), and follow the installer dialog. At version up, if you want to use previous setting, overwrite install is possible. You may need to re-start OS after over write install or uninstall rarely. To install under "Program Files" or "Program Files (x86)" directory, you must start the installer with administrative privileges by selecting "Run as administrator" on right-click menu.
You can uninstall through the Windows OS's Control Panel, or double click unins000.exe in a folder which MultiPar was installed. Because uninstaller does not delete setting files or newly put files, you may delete them by yourself.
When you have used installer package, you should not move install folder. Or else, you will fail to uninstall later.
If multiple users may log-on a PC, the administrator can install MultiPar for everyone. By installing with administrative privileges, installer made Start Menu icon, Desktop icon, and File association will be available for all users. When he installed under "Program Files" directory, each user keeps individual setting. When he installed in another folder, all users share same setting. In either case, user made icons and association are available for the user only.
Unpack compressed file ( MultiPar131.zip or something like this name ) in a folder. MultiPar.exe is the interface of MultiPar.
You can create short-cut icon or send-to link at Option window later. If you associate PAR file extensions ".par" or ".par2" with MultiPar, de-associate them from other application like QuickPar at first.
If you associate PAR file with MultiPar, de-associate them from this. Delete all files in the install folder, in which you extract files. If you installed MultiPar under "Program Files" directory, setting data was saved in MultiPar folder under "Application Data" directory, so you need to delete the folder.
When you integrated MultiPar into shell at Option window, you must clear the check before un-install. If you have deleted MultiPar.exe already, you can un-install the DLL manually. Open "Command Prompt" and change directory to MultiPar's folder, then type "RegSvr32.exe /u MultiParShlExt.dll" to remove shell extension. You cannot delete "MultiParShlExt.dll", while it is used by OS or Explorer. You may log-off and log-on again to OS before deleting the file.
Move files in the install folder. If you associated PAR file with MultiPar, de-associate once, and associate again. If you want to use same setting at another PC, copy the setting file "MultiPar.ini". If you move MultiPar into "Program Files" directory, setting data is saved in MultiPar folder under "Application Data" directory, so you need to move "MultiPar.ini" into the folder, too.
