Hello Shire/cbpporter

I think that windows installer package is uppbox/WinInstaller2.

This package checks if there is an older install just by checking if theide.exe exists. If it is deleted, install will continue (see file Install.cpp, function BOOL CALLBACK Proc( ), line 32)

In addition, when copying files, for any reason the installer appends the files instead of copying over existing files as it uses FileAppend instead of FileOut (see file 7zMain.c, function void LZMAExtract( ), line 95).

These would explain the problems reported by Shire.

Best regards
Iñaki
