Both 7-zip32.dll and 7za.dll are licensed under the GNU Lesser General Public License.
panagenda MarvelClient Upgrade itself is not licensed under GNU LGPL, instead our general terms and conditions apply.
In order to comply with the GNU LGPL terms for above components, we must allow you to replace the above MarvelClient Upgrade components with your own versions, should you wish to do so.
NOTE: We do not support MarvelClient Upgrade if any of the included components are replaced, unless so done by a panagenda consultant and confirmed in writing by panagenda.
In order to replace the above listed MarvelClient Upgrade components, you have two options:
a.) place a 7-zip32.dll file in the same directory as MCUpgrade.exe
b.) place 7z.exe and 7z.dll in the same directory as MCUpgrade.exe
NOTE: The existence of 7z.exe/dll takes precedence over 7-zip32.dll, which again takes precedence over the included components in MCUpgrade.exe.
